Parallax | Layout Comparison | Pin-to-PAP

For this comparison test, I selected three different layouts each with the same pin buffer and PSA values but differing pin-to-PAP distances. I will find the optimal line with each ball/layout and roll similar lines with them to distinguish each ball’s unique layout characteristics.

 

The pin-to-PAP is unquestionably the most influential variable in the layout selection process. It's immensely important to not only look at the innate characteristics built into the balls themselves, but the layouts, most specifically the pin-to-PAP distance, as well. For an in-depth analysis of what pin-to-PAP distances represent in bowling ball layout application, be sure to check out Alex Hoskins' thorough column on the subject here.

I’ve maintained the pin buffer and PSA radii with each of these layouts but adjusted the pin-to-PAP separation across the test balls in 2” increments.

 

BOWLER STATS:

Launch Speed: 18mph

RPM: 480

Tilt:

Rotation: 45°

Layouts Used for Test: 2 x 5 x 1.5 (30° x 2 x 50°), 4 x 5 x 1.5 (60° x 4 x 25°), 6 x 5 x 1.5 (65° x 6 x 20°)

Surface Used on All Balls: 1500-grit Polished

Oil Patterns: 1.) Broadway V2, 37', 4.77:1, 26.45 mL  2.) Tungsten, 39', 6.25:1, 25.60 mL  3.) Beaten Path, 41’, 4.04:1, 24.25 mL


The 2 x 5 x 1.5 layout is an option for players looking for stability. When the patterns are short without much hold and urethane isn't an option, shorter pin-to-PAP distances become the go-to choice. In this instance, the Aeroflo Core is almost completely laid on its side which puts it in a lower RG orientation. The lower the RG orientation, the less resistant the ball will be to changing direction down lane. This type of layout rolls early and smooths out the breakpoint shape; smoothness equals predictability here. The 2 x 5 x 1.5 shined on the shorter pattern, naturally. At just 37' and a 4.77:1 ratio, Kegel's Broadway V2 is short with not much hold. The 5" PSA-to-PAP distance ensures sufficient entry angle and the 1.5" pin buffer provides ample roll through the pins, but because it's still a very stable overall core position, this layout may struggle on lengthier patterns. But if urethane is not your "thing", then consider a shorter pin-to-PAP layout to help control those more compact patterns when the ball tries to dart sideways off the breakpoint.

At just over 4° of entry angle, the short pin was able to control the pocket much better than the other two test balls despite being thrown at the same set down and launch angle. The longer pins simply created too much flare and volatility which made it problematic in the effort to keep them on the right side of the headpin on this short, flatter pattern. Instability in core orientation is what makes a ball hook in the first place, but knowing when and where to use such flare potential remains the bowler's responsibility to determine. 

A 4 x 5 x 1.5 Parallax is a versatile layout that provides a player whose speed and rev rate match an all-around functional ball able to be used on a variety of conditions. On the medium 39' Tungsten pattern, this layout shines. With a subtle change in hand position or speed I can navigate to just about anywhere on the lane with this layout and still get the ball to go through the pins the way I need it to. At 4" from the PAP, this pin distance puts the core in a position that's suitable for most house and challenge conditions. It truly is the best of both worlds connecting early roll in company with backend entry angle. The location of the pin falls between a high-RG and low-RG axis orientation which is considerably unstable. Since the core is wobbling vigorously in this position when rolled, this type of setup yields a dependable motion in the midlane which can be useful in many different circumstances. One can avoid getting caught up in a sudden, unforeseen transition because of this layout's ability to read the midlane and blend out the end of the pattern.

Consistent with the shorter pattern, the 4 x 5 x 1.5 layout shaped an entry angle that fell evenly between the long and short pin test balls. On a middle-lengthed pattern such as Tungsten, I could maneuver left or right and still be in the pocket with a subtle hand position or speed change. The 2" pin and 6" pin were either too soft or to sharp respectively on entry and required a complete zone change in order to get back to the 1-3.

An Parallax drilled with a 6 x 5 x 1.5 creates some serious entry angle. On any pattern, any line, it produced the greatest amount of corner to the pocket. In layouts such as this, there is a very specific time and place they should be used. When the pin is 6" from the PAP, the core is stood up on end internally and in a stable, high RG state. This results in the ball focusing its efforts in the later part of the lane since it is tumbling more. When a ball like this is in a higher RG posture, it will be more resistant to changing direction as it rolls down the lane. Longer pin-to-PAP values raise the RG and encourage a slower transition with a beeline shape through the first 2/3 of lane. Because of this, you'll notice more change of direction down lane. For this test I went with the 41' Beaten Path to show just how vast the differences are in these three layouts. The ideal time I would use a 6" pin layout is when the oil is depleted rather than freshly dressed. This is because the ball isn't slowing down as quickly. With every ball, every throw, energy is lost the moment it leaves the bowler's hand. Other factors that contribute to how quickly a ball slows down include surface roughness of the coverstock and lane materials, but this test is solely looking at core properties. When there's a lot of friction on the lanes forcing the ball to slow down too quickly, a longer pin-to-PAP layout can help combat those conditions because the core is allowing the roll phase to happen closer to the pins.

When the pattern is shorter with more friction for balls to react on, everything tends to hook at same spot. How much it hooks is dependent on things like core strength, layout, surface, etc. On this longer test pattern, the differences in the three balls became even more evident with breakpoint distances and entry angles in line with exactly what you would expect from such layouts. The 6" pin had the latest breakpoint and the most angle, with the 4" and 2" falling directly in line behind the former. 

Here's the drilled and un-drilled RG analysis for each of the balls is showcased below. Based on the above ball motion breakdowns on the test patterns, it's understandable why the 6" pin is the most dynamic of the lot. It has the highest combined differential (total and intermediate). The 2" test ball's total differential was comparable to the other two balls, but its extremely stable core position keeps the aggression in check. The 4" test ball's drilled RG turned out exactly as expected: precisely between the 2" and 6". If I was only allowed to choose one ball for a tournament, it would be the 4 x 5 x 1.5 by virtue of it being the most versatile layout of the three. Always remember, it's your job as the bowler to determine when and where to use such layouts. There's a time and place for every ball, every layout.

As mentioned many times before, whenever a hole is introduced to a bowling ball the RG value of the ball rises in that precise spot. Acknowledging that fact, the results from the RG swing test on the three balls aren't that surprising. The pin up Parallax maintained the lowest drilled RG and highest differential thus, making it the most aggressive of the three. It's also objectively true in ball dynamics that an asymmetrical ball becomes even more asymmetrical if the thumb placement is closer to the PSA. And since balance holes are now a thing of the past, being it's important to be mindful and receptive of where the holes may end up in relation to your gripping holes.

 

Knowledge isn't power until it is applied. Now go apply it!

Axiom - Layout Comparison

For this comparison test, I selected three different layouts each with the same pin to PAP distance but varying pin buffer and PSA values. I will find the optimal line with each ball/layout and roll similar lines with them to distinguish each ball’s unique layout characteristics.

I’ve maintained the pin to PAP distance with each of these layouts but adjusted the pin buffer in 1” increments. The pin to PAP (most influential variable) was held constant at 5” across all three test balls. The CG placement was selected randomly, at best, to better illustrate that static weight sustains little relevance with my style or the conditions I’m bowling on in this test. However, static weight undeniably does matter with “when”, “who”, and "how" variables clearly defined and under certain circumstances, but that’s a topic for a future article.

 

Spinning a symmetrical core around the X-axis (pin) results in the same overall mass distribution no matter where the CG ends up.

The 5 x 5 x 4 layout places the pin directly beneath my ring finger and would all but be referred to as “pin down” at any level in the game. In a brief summation, pin down has historically been known to roll sooner. This conclusion was drawn from the idea that the more static weight was biased towards the thumb caused the ball to rotate off its axis sooner. The antithesis was also widely accepted for pin up balls.

However, the type of technology that commands the contemporary game of today establishes itself on symmetry, asymmetry, and differentials. When static weight was the only ball motion tuning parameter to boost bowling ball performance, it carried a heavier significance. But modern physics dictate that agreement in dimensions, due proportion, and mass arrangement shall have precedence over static weight in bowling ball performance. And because this core has those physics manufactured into it, where the holes are drilled matters more now than ever.

Anytime you introduce a hole into a bowling ball you are raising the RG (radius of gyration) of the bowling ball in that precise spot. When I place holes above and below the pin, I’m greatly affecting the low RG axis of the ball by making the height of the core more like the width. This put the ball’s axis in a high RG orientation and cuts back on overall differential, forcing the ball to roll later rather than sooner and hook less overall. It responds significantly slower to friction, whether it’s to the outside of the lane or at the end of the pattern and blends out extreme transitions between wet and dry. You may have more room for error with a pin down layout as the flare pattern takes longer to finalize and delays the transitions from skid to hook to roll. I prefer playing straighter with larger pin buffers, or when it's late in the block and there's little oil on the lane left to find.

There was only a difference of 1/2° entry angle between these three balls, but over 2 feet of breakpoint distance (front to back) which resulted in either a flush strike or going too high/Brooklyn consistently. Rev dominate bowlers gravitate towards larger buffers due to the lengthened reaction time of the layout. This maximizes their room for error because transition zones with their ball roll are inherently quite short. This gives further credence to the notion that "when" a ball hooks is more important than "how much" a ball hooks.

A pin up 5 x 2 x 2 Axiom sets the pin above my fingers and more to the ring finger side. It was commonly accepted that pin up balls provided more finger weight and delayed the ball’s reaction. As mentioned above, times have changed. Drilling mostly into the high RG axis (Y-axis) of the ball drives the core's width further away from its height by making it taller. This creates a core height that’s even more different than the width that was manufactured in the ball to begin with. This higher “differential” induces greater torque within the ball and forces it to change direction sooner and more overall. You can visually assess this yourself by inspecting the flare pattern on your pin up ball compared to your pin down ball (assuming they’re similar in dynamics).

Pin up balls typically have a greater core orientation benefit when going through the pins because it will likely be in its final roll phase upon impact. And you’ve heard it all before: a ball that’s rolling into the pins has a higher carry percentage than a ball that’s hooking into the pins. Why? Less deflection. A hooking ball still has a skid element associated to it. A rolling ball doesn’t. But pin up balls can sometimes magnify mistakes because their transition zones are so short. Your window for accuracy is now reduced but is still highly dependent on your speed, rev rate, tilt, and rotation.

I like to utilize short pin buffers when I need the ball to get into a roll sooner, especially on heavier patterns. I also like to use pin up balls with longer pin to PAP distances to stand left and throw right because they're ready for friction when they encounter it. If I pull it too far inside into the heavier oil it can still get into a roll and carry rather well. But if I miss right it will still recover all those boards traveled and find its way back to the pocket thanks to its lower RG core orientation and higher overall differential.

Breakpoint distance relationships for the three balls stayed the same with flare potential playing a crucial role in recovery to the pocket. The balls now have to travel a farther distance to get back to the strike zone so the player has to be cognizant of how much the ball is going to hook. Players with higher axis tilts and higher speeds can benefit from smaller buffers by getting it to tilt off its axis sooner. Pin up balls create a low RG band around the X-axis to help it rotate quicker off its axis to combat the slicker oils of today.

An Axiom drilled with a 5 x 3 ½ x 3 naturally drops the pin in my ring finger. This may look like an “exotic” layout, but in reality it’s as ordinary as the other two. Drilling out the pin is preferred over drilling too close or halfway into it because it helps maintain the integrity of the shell and creates a smaller weak point. This mid-range pin buffer distance maximizes proficiency by using the contours of the core to its advantage. For my ball roll and PAP it places finger holes directly in the X-axis and thumb hole very close to the Y-axis, so they reshape the core more uniformly after drilling. I can get the best of both worlds and have found this layout to be one of the most versatile in my bag. With a subtle change in hand position or speed I can navigate to just about anywhere on the lane with this layout and still get the ball to go through the pins the way I need it to. When deciding the layout of your next ball the pin buffer would surely be the second most important variable of the three right behind pin to PAP distance but in front of the PSA's location.

Breakpoint distances remained consistent with the entry angle values branching apart more due to the deeper set down. A 3" buffer can add great versatility to anyone's bag. It's beneficial for just about any style of play. The transition it creates from front to back isn't too fast or too slow. It can also work well on a multitude of patterns. And if it isn't just right, a quick and simple surface adjustment will get it back on track!

And for all you tech enthusiasts out there, the drilled and undrilled RG analysis for each of the balls is showcased below. Knowing what we know now about RG’s and differentials, it’s logical to justify saying pin up balls hooker sooner and more than pin down balls under similar playing conditions. The smaller the buffer, the quicker the ball gets going forward and you can immediately see it in the video below thanks to the low camera angle. Always remember, it's your job as the bowler to determine when to use such layouts. There's a time and place for every ball, every layout.

 

As mentioned many times before, whenever a hole is introduced to a bowling ball the RG value of the ball rises in that precise spot. Acknowledging that fact, the results from the RG swing test on the three balls aren't that surprising. The pin up Axiom maintained the lowest drilled RG and highest differential thus, making its breakpoint the earliest. It's also objectively true in ball dynamics that a symmetrical ball becomes asymmetrical once it's been drilled into and the PSA positions itself close to the thumb once it's been drilled. I've included the new intermediate differential as well. You can see the pin up Axiom also became the most asymmetrical of the group because we squeezed the Y-axis closer to the X-axis but left the Z-axis alone (no balance hole used). From there, lower pin placements (larger buffers) created higher drilled RG's and lower total and intermediate differentials. Knowledge is power. Now go use it to your advantage!

Omega Crux 6 Ways

Watch the video, then read what our employees have to say about it below!

(We're bowlers too, ya know)

 

https://www.youtube.com/watch?v=tU1-9QhhoR4

 

THE CAST:

-In order of appearance-


"The Omega Crux is a ball that I’ve been missing in my arsenal. I was recently refit and have been rebuilding my bags. I like to play straight up the lane, and I throw balls with more confidence when I can miss a little to the right or left with a ball. I also like smooth shapes like an !Q Tour, PRO-Motion, and the Roto Grip IDOL. My favorite pearl asymmetric ball was the Snap Lock and I’ve been looking for a ball that I can trust like I did with it. After a few shots out with the Omega Crux, I quickly realized this was a ball I knew I’d like to throw. In the video, you can see I missed pretty severely on one shot and it still shaped up and struck. I threw it in my weekly league and had the front 10 with it during the second game. I could trust that as long as I got it to the right spot down lane, it would find the pocket. This layout is great for me too because it allows me to stay to the right longer without having to move left."

-Blair Blumenscheid, Communications

 

"The Crux line has been one of my favorites since the original Crux. I see the Omega Crux as a great option when I need to move left and still get the ball back to the pocket.Don’t be fooled, this ball has some teeth, and can make the straightest players move to the middle of the lane, or further!"

-Matt Martin, Senior Designer

 


 

"The perfect blend of coverstock and core shape to give big motion off the spot. I drilled it like my favorite Physix and it was a little sooner and more overall hook than the Physix. Great ball for  flatter, higher volume patterns for me."

-Hank Boomershine, VP Sales/R&D

 


"What more can I say about this ball that Kris Prather didn’t already say himself on TV. It’s super aggressive and allowed me to play multiple angles while creating some amazing pin carry. In fact, for my first 12 shots with it (on camera), I rolled a perfect game with three distinct angles of attack. It’s incredible."

-Steve Kloempken, VP Marketing

 


 

"I was immediately impressed because this ball allowed me to play multiple angles of attack while maintaining optimal pin carry. This is a true testament of how reliable and predictable the Catalyst weight block is and has been for years. The name speaks for itself!

-Kendle Miles, Technical Service Representative

 


"I usually favor knocking the shine off of my pearl balls, and this one comes pre-surfaced to my exact preference! I get both the float through the fronts and the backend traction I need thanks to the GI-20 coverstock. Not to mention the Catalyst Core maintains its integrity better than most asymmetricals thanks to its vertical cavity in the center. I know what I'm getting every time I put a hole in one."

Omega Crux - Layout Comparison

You can't make an informed decision without information. We believe the bigger the idea, the bigger the rewards. The intent of this article is to help you get the most out of your brand new Omega Crux.

 

For this mini-study, I’ve selected three of my favorite layouts. I will also select three different patterns that each ball should excel on and roll similar lines with them to distinguish each ball's unique characteristics:

Each of these layouts give me such distinctive motions that its hard to justify not having one of each (on any particular ball) in my bag at any given time. It’s important to remember that it’s not about how much a ball hooks, it’s about when a ball hooks.

To say “This ball saves a lot of energy” is a misnomer. No ball can save energy. In fact, it’s using energy the very instant it leaves your hand. The more accurate phraseology is “How quickly does my ball slow down?” Start thinking of ball motion in these terms, and things get very easy to understand from here on out.


The 5 x 4 x 3 option is a benchmark layout for me and I’m relying on the pin distance for the bulk of this ball’s motion type. This layout, for my style, excels on patterns 40'+ in length with a defined hook spot. This longer pin to PAP distance, strong PSA location, and medium length pin buffer gives me just about anything I could ask for in a layout. When I want to get left of everyone and bounce the ball off the dry that’s been created to the right of me, this is the layout I’m going to first. All three of the layout parameters are in relatively strong positions, but not too aggressively to the point where it’s uncontrollable or too early reading that the ball burns up. In general, longer pin-to-PAP distances are good to use on the burn when you need the extra tumble through the front part of the lane. This type of layout enables the ball to transition slower and not use too much energy too soon. Remember, there’s 34lbs of pins a 15lb ball must contend with. Capitalizing on the phases of ball motion ensures the ball is transitioning not only where, but when you want it to properly.

 


A 3 x 5 x 1 Omega Crux is thirsty for friction – when it finds it, it’s going to grab and go. Medium length, heavy oil patterns are what I mainly use this layout for. This is largely due to the very strong pin to PAP distance and very small pin buffer. And because my rev rate pushes 500 RPM’s these values are only amplified. A 3 3/8 pin-to-PAP value is, in a manner, the most unstable position any core can be in. High differential, low differential, symmetric, or asymmetric, this orientation is going to wobble more than any other and produce the most track flare. This layout on an Omega Crux is all about the midlane. Moreover, when the lanes begin to transition and you need something to blend out the pattern, this layout can turn the unruliest patterns into a smooth sailing situation. Shorter pin buffers preserve the low RG axis of the ball and raise the already high RG axis of the ball, essentially increasing the overall differential. And because a low RG ball transitions quicker, utilizing the Omega Crux’s already low RG Catalyst Core makes this type of layout an excellent choice for strong, fast transitions when the lanes are demanding. Small pin buffers are excellent for a multitude of reasons!


An Omega Crux with a 0 x 7.5 x 0 layout is unique to be certain. Short, flat patterns without a lot of hold built in are what I would typically use short pin-to-PAP layouts like this on. I’m taking advantage of the lower RG side of the curve with such a layout. And because the core is in an extremely stable position, the ball generally hooks less and earlier on the lane. That combination of facts as they apply to this ball provides me ultimate “hold”. When the core is laid down, its being placed in a more stable position around the low RG axis of the ball. Shorter pin-to-PAP distances promote a faster and smoother transition through the front part of the lane. As such, this earlier rolling, with controlled backends are great on short patterns when you don’t want to see abrupt changes of direction at the end of the lane. The challenge with such a layout is getting the ball to go through the pins the proper way. Because it enters its roll phase very early, you’re going to have to be a scrutineer when it comes to what patterns and surfaces you use it on. Ultimately, if you’re not a fan of urethane, this reaction may be as close as you’re going to get utilizing this type of layout on a reactive. And because the PSA is forced to the maximum distance it can be from the PAP, this ensures the ball still has some continuation off the spot despite the core being in such a stable orientation.


And for all you tech-junkies out there, the pre- and post-drilling RG values for each of the balls are showcased below. And yes, 6.75" is the standard measurement away from the pin a PSA spins up. BUT, as we've said before: SHAPE MATTERS! And the properties of this shape and its mass pushes the PSA to 7.5" away from the pin. Remember, knowing how each hole you place in a ball affects its motion and why it happens makes adjusting between balls all the easier!

INTERESTING FACT:  The O” pin had the highest total differential after drilling, but hooked the least overall because of the core’s low moment of inertia blending out the patterns and the overall stability of the core at the direction of release.

Pitch Purple versus Pitch Black - Internal Review

The Pitch Purple has enough backend potential to hit steep angles and confidently make it back to the pocket.

 

In modern times, Storm has been internationally recognized as the brand who emphasizes the later portion of a ball’s reaction. However, the Pitch lineup has been uniquely different from the start. Looking to expand our performance palette, we started exploring different liquid materials (urethanes) that shifted ball performance. Namely, breakpoint distance, backend hook potential, and entry angle. Depending on who you ask, these factors are arguably the most important variables in modern bowling technology. Storm has the “clean with a kick” look covered, as well as early urethane grip which works exceptionally well on short patterns. Believe me when I say: we’ve been burning the midnight oil when it comes to testing. With Alex Hoskins leading R&D, our lanes have been consistently booked more than ever with new formulas and materials to investigate. There’s plenty of balls that fill the void between a Hy-Road and a Pitch Black, but that something special has been curiously eluding our gaze.

What would happen if we took the same benchmark-cozy Capacitor Core and combined it with a new type of urethane material? The result, as it turns out, was nothing short of amazing. Read in oil, stability in friction, consistency from foul line to head pin was the result. This unique fusion lets you dial in key performance parameters, responding to every input with absolute fidelity.

BOWLER STATS:

Launch Speed: 18mph

RPM: 490

Tilt:

Rotation: 45°

PAP: 5” straight over

Layout Used for Test: 5 x 3 x 2.5 (35° x 5 x 35°)

Surface Used on Both Balls: 1000-grit Abralon®

Oil Patterns: Beaten Path, 41’, 1:4.04, 24.25 mL; Boardwalk, 35', 1:2.16, 28.25 mL

Our curiosity keeps us moving forward, exploring, experimenting, and opening new doors.

 

THE TEST:

For this study, I decided to use Kegel's 41' Beaten Path and 35' Boardwalk. I knew these patterns would showcase the differences between these two balls exceptionally well. I tossed 20 shots on SPECTO with each ball, averaged the results, and created composite motion paths for each along with a comparison chart utilizing the hard data SPECTO provided. Both balls were resurfaced prior to the test using a Surface Factory machine with fresh Abralon pads for each to achieve the most consistent finish possible.

 

41ft PATTERN TEST RESULTS:

Despite being set down two arrows deeper, the Pitch Purple not only covered more boards than the Pitch Black, but still split the 8-9 consistently. Typically, I would never use urethane on anything longer than 38 feet. But the Pitch Purple had just the right balance between the midlane and backend reaction that I could stand anywhere, with conviction, and watch it speed back to the pocket with tenacity. On this pattern, the Pitch Purple produced 17% more entry angle and 23% more length than the Pitch Black.

35ft PATTERN TEST RESULTS:

The most impressive thing about using the Pitch Purple on the shorter pattern was what it didn't do - which was overreact off of the dry. My optimal line was was adjacent to the line I was playing on the 41' Beaten Path pattern. The only adjustment I made was moving up six inches on the approach to dial my speed back smidgen. Furthermore, both balls fell into alignment in the last 1/3 of the lane thanks to the Rev-Controll Urethane cover. Had I been in the same area with even a weaker reactive, it would have been so aggressive off the breakpoint, I would have been leaving designs on the deck I'd rather not have to attempt converting. When my house shots get cliffed during league, the Pitch Purple will unquestionably be my go-to ball. On this pattern, the Pitch Purple created about 9% more entry angle and 14% more length than the Pitch Black.

CONCLUSION:

Have you ever been in a tournament where the top qualifier ran away from the rest of the field not by tens, but by hundreds of pins? Ever wondered how they were able to do that? They more than likely had a niche ball giving them insight into the pattern no one else in the building had. In the simplest terms I can depict, the Pitch Purple not only retains the phenomenal control and feel of its predecessor, the Pitch Black, but it also lives up to the iconic backend motion that Storm is renowned for. This high level of control will provide aggressive players with the license to swing for power. Finesse players will find their mark without fuss while the ball maintains ample power at the pins. The Pitch Purple has enough backend potential to hit steep angles and confidently make it back to the pocket. I was able to stay in my comfort zone on the short test pattern as if I was playing on the longer pattern; all I used was a simple change in speed. This rare combination of urethane midlane with reactive backend is a bonus that makes this ball once of the most “maneuverable” balls to date. If I use anything reactive on a short pattern, it would generally be too sharp/quick off the breakpoint. The Pitch Purple provides the cleanliness of a reactive but is undeniably more forward off the spot, but not to the degree a Pitch Black would be. This equals control not only on short and flatter patterns, but longer more demanding ones as well. I'm particularly impressed with how I can feel the mishits with my hand, but don’t see any drastic changes of ball motion down lane. House shots to sport shots, this ball will have a fixed spot in my bag for quite some time.

Selecting an Arsenal for the USBC Open Championships

If you are heading to Syracuse for the OC’s this year, then you’ve probably already started thinking about what equipment you are toting along. And since ball slots are limited and checked bag fees are high, the gravity in your selection process becomes pretty critical. As with any arsenal, variety is key. Sounds easy, right? Obviously, there’s a lot that goes into it that can become a daunting task for even the most seasoned professional. The boundless options that are available on the market should be used to your advantage, but it all starts with the bowler. Knowing the subtle distinctions in how you roll the ball, such as axis tilt, axis rotation, speed, and rev rate, are most crucial.

Once you’ve determined your stats, next comes the ball selection process. As always, variety is key.

The Open Championships have now abstained from announcing the oil pattern prior to the tournament commencing – which is perfectly fine. You can bet on it not being a cakewalk. Balls that exude control and forgiveness are going to be your best friends with any trip to the OC’s. What kind of balls do this? Well, your favorite benchmark should be the first thing that comes to mind. A low RG, solid, matte finish ball that is smooth and brings the breakpoint closer to the foul line would definitely provide this for the bowler. The !Q Tour is the second longest running ball in Storm’s history for this very reason.

After that, building an arsenal is pretty straightforward. Having a good mix of solids, pearls, hybrids with a combination of surfaces and layouts is important. Typically, you won’t see too many polished balls going down the lanes at the Open Championships. The reason for this all boils down to controlling the breakpoint. Sanded balls maximize your room for error by picking up on the midlane better than polished balls and bringing the breakpoint - the most critical part of the lane - closer to you. It’s not a mystery anymore that surface is the #1 most influential factor that dictates ball motion. The bowlers that perform the best every year will almost always bring a wide array of 500-grit to 4000-grit sanded balls. I’m not saying omit polish completely, so reserve one to two spots in your bag for when they get “toasty” later in the day.

Layouts are the last big thing to discuss. Working with your Storm VIP pro shop professional to establish which layouts are best for your style and the arsenal you’ve chosen is imperative. Some of the most accomplished bowlers will use around three of their favorite layouts and let the inherent properties of the balls be the major difference in what they see. Pete Weber, for example, has only used two layouts for years: one pin up above the bridge and one pin down below the bridge. There are enough factors in bowling that are above and beyond anyone’s control, and, no matter how hard you try, you cannot change them. So keeping the variables in check that you can control, like Pete, isn’t such a bad idea after all.

Below is a sample 6-ball arsenal that would cover all of your bases at the Open Championships this year.


Drive versus Timeless - Internal Review

Zach Trevino loves his Drive, and here's why...

When the Timeless was first introduced, Zach struggled to keep it reading the correct part of the lane before it was too late at the end of the pattern. This is not the ball’s fault, however. His higher ball speed combined with his higher degree of tilt all but promotes skid throughout the lane. Mix in a high RG, polished shell with our cleanest cover (R2S) to date and the struggle becomes very real for a player with his specs. To combat this, Zach took the surface down to match his Drive at 3000-grit Abralon – something he encourages most people who call into Storm to do when experiencing similar difficulties. “I will be the first one to admit that Timeless just wasn’t the ball for me” said Zach. “I drilled one pin up strong and one pin down smoother and it was the latter that only found its way into my bag for one specific scenario - the mega burn.” He added “Using a slower buffer, my pin down Timeless was very useful for when the pattern really got trashed and I had to keep my angles tighter from inside. I don’t have the loft game and often get cornered late in blocks because I have to throw weaker equipment with tighter angles. The Timeless allowed me to bump the dry and it wouldn’t over react when it saw friction. Nonetheless, it was very conditional and didn’t get much use.”

Zach wasn’t the only one who felt “trapped” with the Timeless. Taking this into consideration, we went through many iterations of the intended design with the Drive while ultimately settling on an R2S/Nano blend that we cleverly titled: R2S Nano.

Zach sometimes struggles with stronger covers like this stating they “normally aren’t good for me as it usually results in the ball being too cover driven and just lazy.” However, he later affirmed that his “initial impressions weren’t anything as what I had expected. In this case, that was a good thing! It was as if the ball had so much more shape and read in the mid’s (which Timeless was severely lacking) and just never quit.”

BOWLER STATS

Launch Speed: 17mph

RPM:400

Tilt: 15°

Rotation: 60°

PAP: 4 5/8” over, 1/2" up

Layout Used for Test: 4 3/8 x 5 1/8 x 2 3/4   (65° x 4 3/8 x 45°)

Surface Used for Each Ball: 3000-grit Abralon

Oil Pattern Used for Test: Beaten Path, 41’, 1:4.04, 24.25 mL

RESULTS:

Zach rolled each ball 20 times on Kegel's Beaten Path. We took SPECTO readings at the beginning, middle, and end to compare the results for each ball.

Following his preemptive impressions, Zach started an arrow deeper due to the significantly stronger cover and surface prep. There was never any question the ball would miss the spot from too much length.

After about 10 shots with each ball, Zach felt he should have moved more at this point. Every shot with the Drive was high flush, but a little too high sometimes tripping out the 4-9 several times. The Timeless was the ball Zach felt comfortable with at this point because it was not seeing the friction as severely as the Drive.

SPECTO does a fantastic job of showing the difference in shape with both balls. The breakpoint distances are pretty tightly grouped even though the Drive is over an arrow deeper towards the end of this test. The Timeless needed a straighter trajectory with less launch angle to find the pocket. Overall, Zach preferred the shape and location he had to play with the Drive being inside the track of the Timeless with fresh oil instead of out in the dirt.

Zach has already dedicated a slot in his Open Championships bag for the Drive saying “It is a true improvement as opposed to just being a follow-up with another Belmo logo on it. It’s a unique piece that is going to end up in my tournament bag headed to the OC's this year. It provides that stability and continuous motion needed to control tougher conditions and create area when there isn’t much room for error.”

 

With the same layout and the same surface for 20 shots the Drive, on average, when compared to the Timeless produced:

+6.43 boards deeper set-down

+0.64° launch angle

-1.16° entry angle to pocket

+2 feet of backend

Son!Q versus Marvel Pearl - Internal Review

The Centripetal HD Core delivers instant revs and puts the entire category on notice.

 

Since its inception, the evolution of the design can be traced across the Centripetal Low Flare Core, C3 Centripetal Control Core, and now the Centripetal HD Core. At first glance the Centripetal HD Core may look familiar, but deep down is where the magic truly happens. It is the densest core of any symmetrical Storm ball to date producing an RG value of 2.47. Historically, these renditions of the Centripetal shape have all exhibited a lower RG value with varying degrees of differential achieved by the manipulation of the densities in the core material itself. The Centripetal HD (high density) is the heaviest to date which makes the Son!Q much more center-heavy.  The Marvel Pearl retains the primary shape, but is constructed with a material of lower specific gravity.  What does this mean to you? Let’s explore…

We know that controlling the midlane is what the pros are renowned for. They are able to see ball motion in a way that lets them make the best decision in order to get their ball into a roll before the end of the pattern. Whether they do that with surface, speed, axis tilt, or core technology is dependent on the situation at hand, but believe me when I say having a ball in your hand that is trying to roll as soon as it hits the lanes certainly doesn’t hurt. Chris Barnes, who’s arguably the best technician on tour, told me years ago that he only uses low RG balls for this very reason.

A ball that is rolling into the pins carries considerably better than a ball that is hooking into the pins. When a ball makes impact and doesn’t have a direction of motion that is in-line with the centers of gravity of the pins, some of the energy that would have been available for the post-collision pin velocity will be lost to rotation and friction. Because the Centripetal HD Core’s center of gravity is extremely low, it consistently impacts the pins at the perfect spot every time maximizing carry.

Delving a little deeper into the physics behind it, angular momentum is much harder for an external force to change its direction as opposed to linear momentum. Angular momentum is essentially the rotational equivalent of linear momentum and remains constant unless acted upon by an external torque that’s proportional to the initial moment of inertia (the bowler’s release). The faster the angular momentum created, the more torque is required to cause a change in angular acceleration. Simply stated, we apply rotational energy to create angular momentum around the weight block of a bowling ball, AKA torque. This energy we impart on the ball stays the same until something else tries to stop it, like the friction on a lane or 40lbs worth of bowling pins. Cores like the Centripetal HD in the Son!Q that have lower RG values have a higher potential to conserve its angular momentum throughout the lane and into the pins. This results in less deflection, better carry, and higher scores.

Getting into something that’s a tad more observable to the naked eye, the entry angle into the pocket that the Son!Q creates really wasn’t that steep. Especially when compared to something like a Hy-Road Pearl that’s at the other end of the spectrum when discussing RG values. Balls like the Hy-Road Pearl, at least for me and the way I roll it, really magnify both wet and dry circumstances which is probably why they only time I use the ball is when there is at least 2000-4000 surface on it. With the Son!Q, I noticed less wrapped 10-pin leaves, fewer stone-9’s, and much lower flight paths of the pins when the ball makes contact – which was optimal for carry in my many off-pocket hits because the pins are colliding with each other instead of flying above one another. On the rare occasion I left a stone-9, there was always a messenger there to greet it.

BOWLER STATS

Launch Speed: 18mph

RPM: 490

Tilt:

Rotation: 45°

PAP: 5” straight over

Layout Used for Test: 5 x 6 x 4  (80° x 5 x 60°)

Surface Used for Each Ball: 1500-grit Polished

Oil Pattern Used for Test: Beaten Path, 41’, 4.04:1, 24.25 mL

 

RESULTS:

For this test, I tossed 30 shots with each ball on a fresh Beaten Path pattern and took excerpts from each transition you can see below in the SPECTO results. Even just a 0.010 difference in the low RG versus the Marvel Pearl was enough to make the Son!Q breakpoint distance a couple feet sooner during my initial warm-up when getting lined up. But for this test, I wanted to show the best line to the pocket for both balls on the Beaten Path pattern by Kegel. Early on (fig.1), the Son!Q’s lay-down had to be about 3 boards inside of the Marvel Pearl. From slightly inside, the breakpoint distance was 1-2 feet later for the Son!Q, but it was also crossing more boards overall given the same speed and hand position I was using.

As the lane started to transition (after about 12 shots) I moved the standard 2:1 and found no shortage of movement or carry with either ball. The Son!Q laydown remained just inside of the Marvel Pearl with the breakpoints inching closer to one another downlane (fig. 2). The R2S cover on the Son!Q was able to generate slightly more entry angle into the pocket due to its cleaner nature when compared to the R2X featured on the Marvel Pearl.

After another 12 shots or so I moved another 2 left but kept my eyes the same. At this point, the breakpoint distance for both balls were well-nigh similar and the breakpoint boards were pretty close as well (fig. 3).

The differences in the two balls, for me, shined through on the fresh. When the lane started to really break down, the spread between the two got closer with the additional friction that was happening in the fronts. If you already have a Marvel Pearl but are considering picking up a Son!Q, I would recommend another one of your favorite layouts or a simple surface change just to give yourself a little more diversity in your bag - unless a 3-5 board shift inside and a slightly more angular downlane transition is what you are looking for given equal layouts/surfaces. To date, the original Marvel Pearl @ 3000-grit Abralon was my favorite “on the fresh” ball. Now that the Son!Q has made its way into my hands, I will keep it at the original 1500-grit polished surface and use it to fill that transition gap I’ve been combating for such a long time and reintroduce my Marvel Pearl back to 3000-grit.

 

With the same layout and the same surface for 30 shots the Son!Q, on average, when compared to the Marvel Pearl produced:

+2.48 boards deeper set-down

+0.030° entry angle to pocket

+1.16 feet of backend

Pin Up vs. Pin Down

What should I do?

“Should I drill this ball pin up to give me some extra length, or pin down to give me an earlier roll?” A vast majority of bowlers today generally make this their primary decision when drilling a new bowling ball. If you’ve ever been in the pro shop business, you’ll hear it all the time.

With so many changes to bowling ball technology over the last 30+ years, what do those changes in layouts really do to ball reaction?

Bowling ball technology has evolved over time making some of our older theories not quite as relevant to today’s game. In order to understand what has changed, let’s take a step back in time and look at bowling ball technology in the early years of bowling.

Past and Present

Early day bowling balls did not have heavy dynamic shapes to create large flare patterns. Take a look at Figure 1. The picture on the left is an example of what the inside of a majority of bowling balls looked like 30+ years ago. They consisted of a small slug at the top of the ball which the fingers and thumb would be drilled over to offset the weight lost from drilling. Since this was the primary shape causing imbalance, static weights such as finger and thumb weight were much more relevant to ball reaction.

When drilling a ball pin up, it would generally have more finger weight. This caused the ball to get down the lane a bit further. When you drilled a ball pin down, it would generally have more thumb weight. This caused the ball to react a bit sooner. The static weights were much more influential because there was nothing else inside the ball for gravity to influence.

Fast forward to today’s game. Take a look at Figure 1 again. The picture on the right shows the inside of a modern day bowling ball. We now have large, dense, and dynamic shapes that dominate ball reaction. We can now create vastly different reactions using different drilling layouts. The laws of physics cannot be broken. Our main concern with the powerful cores of today’s game is the radius of gyration (RG) and differential (Diff). These two work together with other variables to create 3 distinct phases of ball motion as the ball travels down the lane. While there are other variables influencing these phases of ball motion, we are going to hold them constant for the time being and focus on this piece of the puzzle.

The Pin Buffer

Before we understand what the reaction differences between pin up and pin down layouts are, we need to know what is actually changing in the layout that causes the pin to be above the fingers compared to below the fingers. Take a look at Figure 2. It may look like a lot to take in at first, but it's a great illustration of the difference between pin up and pin down. We can have two different balls with an identical Pin-to-PAP distance and MB-to-PAP distance, but one has the pin above the fingers the other has the pin below. The cause of the change is the final measurement in Storm's Pin Buffer Layout System, the pin buffer. Shorter pin buffers are going to raise the pin because they have to be closer to the VAL. This is seen in the ball on the left in Figure 2. Longer pin buffers are going to lower the pin because they have to be further from the VAL. This is shown by the ball on the right in Figure 2. The only difference between these two balls is the pin buffer. The ball on the left has a 2" pin buffer, while the ball on the right has a 4 1/2" pin buffer.  You can see that the pin is forced further down the farther away it gets from the VAL and further up when it is closer to the VAL. Now that we understand what is causing the difference in the layout, let's take a look at some of the key differences in dynamics that result from putting the pin above the fingers compared to below.

Removing the Mass

When drilling a bowling ball in today’s game, it is important to note where the mass is being taken out of the core. Every hole you introduce to the ball is going to alter the shape of the core. This means the RG and differential are both going to change from the undrilled number. Refresh your mind by looking at Figure 3. As we know, the pin is the designation for the x-axis on the surface of the ball. It is the very top of the core. Approximately 6 3/4" away from the x-axis is the y-axis. This is 1/4 of the ball and gets us directly into the side of the core. Total differential is measured as the difference between the x-axis and the y-axis. Essentially it is a measure of the difference between the height and width of the core. The larger the difference, the higher the total differential. More differential means that there is the possibility for more imbalance and flare if the core is positioned appropriately from the PAP. Getting back to the topic of this article, let’s take a look at how we change these core dynamics with pin up and pin down layouts.

Take a look at the example that we have shown in Figure 4. It's a basic example, but you'll notice the pin is above the fingers. This is going to result in the holes being drilled more to the side of the core. This means that more mass is going to be taken out of the side of the weight block than the top. This is essentially making the weight block thinner than it was originally. The larger the hole, the more influence it is going to have. You'll notice on most pin up layouts, the thumb hole ends up being close to 6 3/4" away from the x-axis. As you can see, this increases the difference from the x-axis to the y-axis. This raises the total differential and keeps the RG lower than it would be if the holes were in the top of the weight block. We know a lower RG ball is going to transition faster because it is less resistant to changing direction. Think of an ice skater with their arms in. They spin extremely fast because a majority of the mass is located towards the center. This is going to result in the ball revving up faster and flaring more. Overall, this will make the ball stronger and transition faster off the spot.

Take a look at the example that we have shown in Figure 5. A pin down layout is going to result in the holes being drilled more on the top of the core. This means more mass is going to be taken out of the top of the weight block than the side. This is essentially making the weight block shorter than it was originally. You can see how you are now moving the thumb hole away from the y-axis and drilling the fingers nearly on top of the x-axis. As you can see this decreases the difference from the x-axis to the y-axis. This lowers the differential and raises the RG. We know a higher RG ball is going to transition slower because it is more resistant to changing direction. Think back to the ice skater. If they put their arms out, more mass is away from their center. This makes them slow down and requires more energy to be added in order for them to spin at the same rate as they did with their arms in.  This is going to result in the ball revving up slower and flaring less. Overall, this will make the ball weaker and transition slower off the spot.

Finishing Up

The days of a pin up ball going farther down the lane and a pin down ball starting sooner are gone if we hold the other variables constant. The changes in bowling ball technology over the years have significantly altered how drilling the bowling ball will influence ball reaction. These large dynamic shapes now dominate ball reaction and overpower static weights. Modeling these two different layouts on our engineering software, we were able to change the differential a significant amount. Prior to drilling, a 15lb Velocity Core has a differential of 0.051. When we modeled the pin up layout, the differential went up to approximately 0.057. When we modeled the pin down layout, the differential went down to approximately 0.035. As you can see, where the mass is taken out of the weight block and how large the holes are makes a tremendous difference on the specs of the core. The main idea of this article is to get you thinking about the cause and effect of drilling a ball in today’s game. Every hole you introduce to a ball is going to alter the shape. Are you altering the shape in a way that matches up to how you throw the ball or what you bowl on? Again, we know that there are many more pieces to this puzzle. All we can do is take a look at each of the pieces one at a time to fit them all together to see the entire picture.


PIN-to-PAP Distance

Decisions Decisions

There are many decisions that need to be made after purchasing your newest bowling ball. All of them are pieces of a puzzle that fit together properly to create good ball motion. The Pin-to-PAP distance is going to be the first and one of the most important decisions that should be made regarding the layout. Of the changes you can make to a layout, Pin-to-PAP distance is going to have the greatest effect. If you are starting to build a new arsenal, it is best to take a look at some of your current equipment to see what types of Pin-to-PAP distances you have been utilizing. You may notice you prefer certain distances over others. You might find that all of your equipment utilizes a similar distance. Does that distance match up well to your ball speed/rev rate or the conditions you are bowling on?

Pin-to-PAP distance might happen to be the piece of the puzzle that was missing for you.

After reading this article, you may begin to understand why you struggle on certain conditions. The goal of this article is to open your eyes to experimenting with different Pin-to-PAP distances to create different shapes. Let’s take a look at some background information on what the Pin-to-PAP distance is and how it affects ball reaction.

 

Orientation of the core

The Pin-to-PAP distance (appropriately enough) is the distance from your positive axis point to the pin. It is going to control how much of the core's flare potential you utilize in the bowling ball. It is controlling how the core is oriented at the moment of release. The Pin-to-PAP distance can range anywhere from 0 to 6 ¾". You might notice that this is approximately 1/4 of the bowling ball. We have turned the coverstock and core translucent in the above figures to show you the orientation of the weight block with different Pin-to-PAP distances. It's important to note that these do not take into consideration axis rotation or axis tilt. They are simply rolling forward with 0 degrees of both axis rotation and axis tilt. Figure 1.1 shows the position of the core at release with a 0" Pin-to-PAP distance. We've put a green dot on the weight block to aid in visualizing the rotation since there is minimal movement. This illustrates how stable the weight block is upon release and why it doesn't create a significant amount of track flare. It is rotating around the lowest RG axis. Skip over to Figure 1.3. Once again the weight block is in an extremely stable position. It is standing completely up rotating around the highest RG axis. Figure 1.2 illustrates the rotation of the weight block exactly halfway between these two points at 3 ⅜". The weight block will be in the most unstable position because it is sitting at a 45-degree angle inside the ball at the release point. This is going to result in the highest amount of track flare that particular core can produce. Different cores are going to produce different amounts of flare depending on the amount of total differential in the shape of the weight block inside of the core. Simple shapes can produce as little as 1" of flare. More complex shapes can produce upwards of 6" of total flare on the bowling ball. Now that we know the flare potential of the bowling ball can be manipulated using different Pin-to-PAP distances, we need to see what happens on both sides of the RG curve to understand why a ball can flare the exact same amount, but give us two completely different shapes down the lane.

 

Strong pin-to-pap

Figure 2 shows the general position of the core with a strong Pin-to-PAP distance. You can see that a Pin-to-PAP distance of 3 ⅜" utilizes 100% of the core’s flare potential because it is sitting in the most unstable position at the point of release. This is going to cause the core to wobble more than any other position which produces the most track flare. Stronger Pin-to-PAP distances are going to give you a strong predictable motion that you can count on in the midlane. This can be good in many different situations. One that comes to my mind is when the lanes are transitioning and you need something to blend out the pattern. Depending on the lane surface and volume of the oil pattern, you can even get away with these stronger Pin-to-PAP distances on some shorter patterns because it revs up strong in the midlane and blends out the end of the pattern. If we move up the curve, we increase the distance from 3 ⅜" towards 6 ¾" we utilize the higher RG side of the curve. As we get closer and closer to 6 ¾", the flare potential in the bowling ball is lowered because we are putting the core in a more stable position. This results in the ball hooking less and later down the lane. This happens because we are standing the core up in a more stable position about the higher RG axis. The higher the RG, the more resistant the ball will be to changing direction as it travels down the lane. Using longer Pin-to-PAP distances is going to raise the RG and promote a slower transition with a cleaner shape through the front part of the lane. You will see more change in direction down lane with longer Pin-to-PAP distances.

 

long pin-to-pap

Figure 3 shows the general position of the core with longer Pin-to-PAP distances. In general, longer Pin-to-PAP distances are good to use on the burn when you need the extra tumble through the front part of the lane. The ball is going to want to conserve energy much longer and transition slower. As soon as the bowler releases the ball, the energy the bowler imparts on the ball will begin to be lost. Controlling how quickly the energy is lost is crucial to creating good ball motion. There are more variables than just the Pin-to-PAP distance that influence the rate that energy is lost, but for this article's purpose we are simply looking at this one piece of the puzzle. Using too strong of a Pin-to-PAP distance when the pattern is extremely dry will result in the ball losing too much energy too early on the lane. It is going to be very difficult for the ball to get through the pins properly when it has used up a majority of its energy in the front part of the lane. We only have 15lbs of ball to knock down 34lbs of pins. We need the ball to be in the proper phase of ball motion at the correct entry angle to win the battle. To accomplish this, you'll want to make sure you are using longer Pin-to-PAP distances when the lanes are drier to promote a cleaner look through the front with more energy down lane. This will allow the ball still have enough energy to make it around the corner and get through the pins properly. Keep in mind there are always exceptions in our game, but this gives a good generalization to get your mind headed the right direction.

 

short pin-to-pap

Figure 4 shows the general position of the core with shorter Pin-to-PAP distances. The more we begin to decrease the distance from 3 ⅜" towards 0" we utilize the lower RG side of the curve. As we get closer and closer to 0", the flare potential in the bowling ball is lowered because we are putting the core in a more stable position. This will result in the ball hooking less and earlier on the lane. This happens because we are lying the core down in a more stable position about the lower RG axis. The lower the RG, the less resistant the ball will be to changing direction as it travels down the lane. Using shorter Pin-to-PAP distances is going to promote a faster and smoother transition through the front part of the lane. You will see a much earlier roll with not much direction change down the lane if you utilize shorter Pin-to-PAP distances.

In general, this would be good to use on either the fresh, or a very short pattern where you are looking for control off the end of the pattern. The ball is going to get into a roll extremely early because the core is laying in such a stable position around the lowest RG axis. This means that it will use a lot of its energy early and smooth out the reaction down lane. This can be great when the lanes are really flat and you are looking to stay out of trouble. You will get a smooth predictable reaction out of shorter Pin-to-PAP distances. Of course, it could be a bit of a challenge to get them to go through the pins properly because so much of the energy is used in the front part of the lane. Remember, we have a 15lb ball against 34lbs of pins.

Luckily modern day bowling balls cause lane patterns to transition extremely fast.

The bowler should be able to move from these shorter Pin-to-PAP layouts to other layouts that will give them more shape down lane. Shorter Pin-to-PAP distance layouts definitely aren't what you want to have on every ball, but they can save you from the dreaded 150 game on the fresh or when the pattern is extremely difficult. That could be the difference between winning and losing. It's not always the ball that you throw in the finals that got you the win. Sometimes the unsung hero is the ball that keeps you out of trouble when the lanes are tough. A good arsenal is always going to have at least one shorter Pin-to-PAP distance ball for control.

Symmetrical verses Asymmetrical

One final topic that must be addressed when discussing Pin-to-PAP distance is the different effects it has on a symmetrical ball verses an asymmetrical ball. Figure 5 shows the difference between a symmetrical shape and an asymmetrical shape. Since an asymmetrical ball has the presence of a preferred spin axis (PSA) there can be significant differences when using longer Pin-to-PAP distances. These differences depend on the location of the PSA. If the ball driller puts the PSA in a weak position, longer Pin-to-PAP distances will react similar to a symmetrical ball. If the PSA is placed in a strong position, the ball will actually flare more with longer Pin-to-PAP distances than they will on a symmetrical ball. This is just another example of how much more versatile some of those asymmetrical shapes are. They can be fine-tuned further than a symmetrical ball to get a closer match to what you are looking for.

Wrap-up

Concluding this article, we can see that the Pin-to-PAP distance is a powerful tool in creating proper ball motion. It controls how much flare and what side of the RG curve we use. A problem many bowlers have when they run into issues with carry is their ball either still hooking or being completely rolled out at the pins. There is a small window in there where the ball is in a strong roll. A ball is always going to transfer more energy if it is rolling through the pins. We are bound by the laws of physics in our world. We have 34lbs of pins is standing in the way of a 15lb bowling ball. The pins are always going to win unless we get the ball into the roll phase at the correct time and at the proper entry angle. Pin-to-PAP distance is going to help you control how much energy your ball has and where it begins to use it so you can begin to create the proper shape and entry angle. Always be sure to have a few different Pin-to-PAP distances in your arsenal to be sure that you can create the right amount of flare for anything you are bowling on. As previously stated, there are many more variables that influence ball motion. This article looked solely at Pin-to-PAP distance and held other variables constant. This is just one piece of the puzzle to creating good ball motion. Future articles will cover other pieces of the puzzle to help you understand the entire picture.
