The Crux Prime delivers the power and flare the line is known for, but has a few surprises up its sleeve to offer a bit more control.


The PhysiX and the Crux Prime have more in common than one might think – performance being one of the lesser accords. Let’s take a trip down Memory Lane and see how their genealogy relates, shall we?

The PhysiX features a coverstock that has never been introduced to the United States until now, and a core that the world has yet to see: the Atomic Core. At first glance, the Atomic Core automatically connects itself to the Storm brand. There’s no doubt where this shape came from! But it’s not all pizzazz. The inlets surrounding the classic Oval Bolt actually do serve a purpose. They form very large RG bands the ball doesn’t want to deviate away from as its rolling towards the pins. This creates a ball motion that is tough for 35 pounds worth of bowling pins to exact their will upon.

Review: Hank Boomershine on the Atomic Core

NRG Hybrid has never been put on a catalogue featured, domestically released ball. So it’s fitting that it is featured on a shape that very well may be the most iconic design to ever leave Brigham City, Utah.

We’ll admit, behind the scenes, we were indecisive as to what cover we were going to wrap the Atomic Core in when it was time to unveil it to the public. I mean, when you have so many good ones at your disposal, it makes it kind of hard to decide! We don’t develop balls just to develop balls; each one has a specific purpose with a design intent. So during the time of development, Bowl Expo 2018 was just around the corner in Las Vegas, Nevada. We decided to take the top three coverstock contenders that could potentially marry with the Atomic Core and let the public decide this ball’s fate. Keeping the core a secret, NRG Hybrid was the eventual winner based on the feedback we received from the public testing and the PhysiX became so. What were the other two test covers, you ask? One was R2S and the other that came in second place by photo finish is what we refer to as “SPEC” today. Believe me when I say we are always testing experimental shapes and fascinating covers here at the bowling ball factory. The Catalyst Core was a design that the masses were demanding to be brought back and what better way to do it than with an all-new cover!

The vertical cavity that’s nestled in the center mass of the Catalyst shape acts as a deliberately-placed balance hole which is very user-friendly when you’re able to drill into it and not affect its dimensions too much.

The Crux Prime has all the ingredients of a dangerous weapon from the baseline.

The chemistry behind SPEC is enough to warrant its own full-length seminar, so we won’t dive too hard into the details here. But it is important to note that this material grips the lane unlike anything that has ever left the Utah plant. In a nutshell, the innate Ra of SPEC is slightly higher than our other primary coverstocks that don’t use an ancillary additive or enhancer. Chemical friction, surface roughness, and COF’s are commonalities in the bowling game we know today. But there is another component to bowling ball development and performance that ties in directly to the endless tapestry that is ball motion: chemical tackiness. For instance, a pearl/polished ball has a very high dry lane coefficient of friction. A ball like this is extremely tacky when it encounters arid lane material. Put this ball on oil, and its COF becomes almost nil. SPEC material, however, creates virtually the same adherence on dry lane material at any given surface. This extra “cling” the ball produces gives the wielder added bearing and control especially when needing to get the ball to shape properly after moving in deep with heftier launch angles. The result is sustained entry angle into the pins and prevention of the ball migrating forward too quickly (rolling out). For lack of a better term, this “cohesion factor” the Crux Prime creates when it touches the lane largely makes up for the decline in surface profile which results in a minimal loss in backend reaction over time.


Now that these balls have names and directions, it’s time to dive into the nitty-gritty an expose as many details as we can about the Crux Prime and PhysiX.



BOWLER STATS:

Launch Speed: 18mph

RPM: 490

Tilt:

Rotation: 45°

PAP: 5” straight over

Layout Used for Test: 5 x 3 x 2 (35° x 5 x 30°)

Surface Used on Both Balls: 3000-grit Abralon

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

The layout chosen for these two balls was 5x3x2. As always, Storm’s VLS system is an original conception and is the only layout system in the industry that takes the shape of the weight block into account.

 

THE TEST:

For this study, I decided to use Kegel’s 4:1 Beaten Path. I knew this pattern would showcase the differences between these two balls exceptionally well. I tossed 30 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 Storm Surface Factory machine with fresh Abralon pads for each to achieve the most consistent finish possible.

 

THE RESULTS:

The Crux Prime breathes new life into the Premier line with the never-before-seen SPEC coverstock. There were some palpable differences between the Crux Prime and the PhysiX that challenges the conventional way we think some of these chemical formulas behave. I found this the case both objectively and subjectively. Let’s refer to the former, shown below.

Solids are widely accepted as balls that require heavier volumes to perform as intended, comparatively to pearls and hybrids. The Crux Prime naturally settled me about 5 boards deeper than the PhysiX, but the interesting part was what happened on the backend. At over a degree more entry angle at the point of impact, the Crux Prime left me astonished time and again. This really came in handy when I started to see the ball checking a little early and I crept inside to find my easy float through the fronts once again. This doesn’t make the PhysiX a bad ball or under-performer by any means, there’s a time a place for each and every ball. NRG Hybrid has an innate chemical friction built into its substructure thanks to the Nano additive we utilize in it. This makes the ball want to lose its axis rotation fairly quickly (higher rev rates only amplify this) so the PhysiX set down point was always just outside the Crux Prime for me. With its earlier breakpoint, the PhysiX at 1000 or 2000-grit would be enough to tackle the heaviest of the heavy that I would ever see here in Northern Utah.

 

The chemical adhesion (mentioned earlier) the Crux Prime creates to the lane is observable and very much welcomed. Its able to maintain its mid-lane read with no shortfall of entry angle. We all look for that “unicorn” reaction where the ball is clean through the fronts, strong mid-lane, great continuation through the deck, and hits like a truck. If you are reading this and you’ve found the prodigal ball that does it all, please drop me a line because I will pay dearly for it. If there was ever a ball I’ve rolled that does it all and then some, this is as close to that fabled reaction I’ve ever seen. The tackiness it seemed to produce when it encountered dry lane kept the ball from jerking too hard off the spot. “Controllable angle” sounds like an oxymoron, but the Crux Prime provides it with ease. I can’t wait to see how this coverstock performs on future cores – symmetrical and asymmetrical alike.

 

CONCLUSION:

True to its heritage, the Crux Prime continues to impress me every time I pick it up. When I needed to be aggressive and step in to sling the ball farther out, I could tap into the Catalyst Core’s power potential with as little effort as moving up 6″ on the approach. I also liked the response of the cover when I was looking for friction up front. I felt accurate with the Crux Prime in my hands, and I was confident from multiple angles. Overall maneuverability was excellent, which made it very easy to get my swing into position and free up my grip. The out of box 2000-grit surface demands a pretty slick environment to thrive on, so taking it up to 3000-grit for this test was a good decision as I see myself being able to use it on a wider variety of conditions and in different bowling centers. There was enough of a difference between the PhysiX and Crux Prime for me that I would justify reserving a spot for each in my bag when traveling to future tournaments.
