Crux Prime
« on: January 23, 2019, 12:30:13 PM »
Storm has brought back the Catalyst Core in the Storm Crux Prime high performance bowling ball. This popular core has been known for its unmatched power, increased entry angle, as well as allowing more room for error due to dynamic asymmetrical design and vertical cavity technology. The SPEC coverstock used in this ball stands for Storm Performance Enhanced Coverstock. This special coverstock was specifically designed to endure the friction and oil a bowling ball goes through each time it is thrown down the lane. The SPEC Solid Reactive coverstock used on the Crux Prime is best used on heavier oil conditions and really shines when the lanes start to transition. No matter what lane condition this ball faces it will consistantly read the midlane and store energy for the backend.

Color: Red/White/Purple
All colors do vary somewhat from the picture shown
Core: Catalyst (Asymmetrical)
Coverstock: SPEC Solid Reactive
Finish: 2000-grit Abralon
RG: 2.50
Differential: 0.052
** RG and Diff are based off of 15 lb. balls
Recommended Lane Condition: Heavy Oil
Fragrance: Poemgranate Cider

The Crux line has always been a favorite to me. With the release of the Crux Prime I was really excited to have this option back in my bag. I drilled mine 50 x 5 x 30 out the box this ball was super early for me. Changed the surface to 3,000 and allowed me to see better results! It's a nice step up from my Physix when I more ball in my hand. Great ball to add to your lineup if you're looking for a high performance ball!

Crux Prime review - Mark Tarkington

Right Handed
Ball weight:  16
Rev Rate:  400
Ball Speed:  17
Axis Tilt:  7
Axis Rotation:  45*
PAP:  3 3/4 horizontal, 7/8 up
Layout:  50 x 4 Ĺ x 50

The Crux series has been very good to me.  Iíve had all of the worldwide releases and one of the overseas releases.

Each Crux I have has a very specific and distinct reaction.  The covers are so diverse between them, Iím able to usually find one that works on many patterns.

Enter the Crux Prime with the Spec cover.  Same fantastic core, new coverstock.  Used one of my go-to layouts for big asyms and have not been disappointed.   Iíve used it on a variety of THS patterns in many houses and this cover may make it the most versatile of all worldwide releases (Crux series).  Out of box, my reaction was great.  It gave me the normal Ďstand left throw rightí look on most house patterns.  This core rolls through the pins better than most for me.  It just seems to match my game really well.  As it began to lane shine, after about 15 games, it was getting additional length, so I started tweaking the shell to see what else I can get out of it.  Iíve had it as low as 1000 and high as 3000, but have yet to shine it up.

This iteration of the Crux rolls great like all of the series, but I believe the new Spec cover may last longer than the GI-16 or ERG covers from the previous releases.  Iím going to continue to put games on this one and see how long that cover will last. 

Since drilling, Iíve carried this ball to every tournament that Iíve rolled and there arenít many times that I havenít been able to use it at some point.  Iím going to enjoy rolling every game I can with this one.

Storm Crux Prime Ball Review by PJ Haggerty

If you need a ball for heavier oil conditions, the Crux Prime is the ball you need to drill.  With the same engine as the Alpha Crux and a brand new coverstock (Spec), the Crux Prime is designed to dig in the mid-lane and not stop hooking.  After drilling two of them, Iíve seen first hand it does exactly that.

The first one I drilled is mapped out as 5 Ĺ x 5 x 60 @ 3000 with water.  With that layout and surface, Iíve seen the response time get quicker.  Since so much urethane is going down the lane these days, I think the Crux Prime can help by still going through the pins the right way. 

The second one I drilled is mapped out as 6 x 4 x 70 with a very tall pin above my bridge and the mass bias right by the thumb.  I hit it with a 2000 pad and this layout gives me a very controllable and forward motion.  My response time is slower on this ball, but it doesnít slow down through the pins.

All in all, if you need a ball to fight through oil and dig in the mid-lane, the Crux Prime should be the next ball in your bag.

PAP - 3 5/8 up 1 1/8
Speed - 16
Tilt - 17
RPM -400

Storm's new ball in the premier line is the Crux Prime.  It comes with all new coverstock called SPEC with the same core that is in the Crux line - Catalyst.  I drilled mine 5.25 x 4.5 x 4.5 pin down.   For me the motion of the Prime is very strong overall.  But for a solid ball it still gives me good backend motion and just keeps going through the pins.  Some bowlers are comparing the Prime to the Alpha, but for me the Crux is 3-5 boards stronger.  I think the Prime will be a very good choice for S/D at Nationals this year.  I have drilled a lot of these balls for all types of styles with great results.

Crux Prime

Layout: 60 x 5 x 40
PAP: 4 1/8 up 1
Speed: 18

This ball has gotten a lot of hype due to the core inside and it has not been a disappointment. I went with a longer Pin from Pap than other Asymmetrical Solids (Halo, Sure Lock) which allows this ball to get through the front part of the lane and a little more angular than normal for me. This ball is a perfect replacement for the Alpha Crux but it does more than that ball. I see it tumble through the front but continue on the back which will be the perfect shape I want for flatter patterns. I have seen success with this ball with added shine but I have decided to keep mine at 2000 to compliment other pieces in my bag.

My stats are in my profile. I laid the CRUX PRIME out 65x5x35. This is my preferred initial layout on big core asymmetric bowling balls. I have been touching the surface up with 2000 when it shows a little lane shine.

For me I have mainly been throwing the PRIME on a sport condition league that is 45' this half. The PRIME can be very slow off the spot if I am lazy with my release. Compared to a PHYSIX that has 45x4x30 layout, the PRIME was slow at the point. I went ahead and put a balance hole 6 3/4" from my pin down the VAL. Different bowling ball with the balance hole. The PRIME is more responsive at the break point and can be a little sharp. The strong cover does let me play the hold on this longer pattern which is better for my game as I tend to miss left more than I do right.

I have been balling down with either the PHYSIX or new RG HALO PEARL depending on how much we chop up the track with surfaced balls.

Drill this one if you want a strong ball that responds to your grip pressure. If you hit it the PRIME will hook, if you lay off, the PRIME will stay online and be predictable. all in all, this should be a good sport shot type ball because it is controllable and does not naturally break loose at the end of the pattern even on the fresh unless you "get on it" at the bottom and make it hook sharply.

Pin Length: 3- 4 
Starting Top Weight: 3.1 oz
Ball Weight: 15
Pin buffer 5 inches

Rev Rate:  380-420
Ball Speed: 15-16
PAP/Track:  PAP:  5 13/16Ē and 1/2" up
Box Finish: 2000 Abralon
The Crux Prime has increased entry angle, and a greater margin for error with its dynamic asymmetrical design and vertical cavity technology. The benefits of SPEC Solid Reactive can be truly appreciated on heavier conditions, especially when they begin to transition. When this coverstock encounters midlane friction, it digs in harder, unlike anything Storm has produced to date
This ball is really strong in the midlane and goes through the pins better and more consistent than any ball I have drilled yet. This ball seems to match up to straight players as well as high rev players. This balls works well on House shots as well as Sport shots. If you need a stronger ball in your arsenal the Crux Prime is a must!

The Crux Prime is the latest high performance bowling ball in the premier line from Storm. The Prime uses the same Catalyst core that was in the previous Crux balls, but this time, wrapped with an all new to the industry cover stock formula called Spec. This new formula of solid reactive material produces a lot of hook, with less oil absorption than other formulas and comes from the factory with a 2000 grit abralon finish. In a nutshell, the Crux Prime is a big hook ball that is also built to last. The Prime has an Rg of 2.50 with a differential of 0.052, and intermediate diff of 0.017, in 15lb bowling balls.

I drilled my Crux Prime using a 4 x 4 x 3 layout. Comparing the Prime to a Physix with a
4 x 5 x 3 layout, both balls were in their respective factory finish, although the Physix has about 35 games on it. I drilled the Prime and went to league the next night with an open mind and no expectations. I had been using the Physix, and been doing very well on this higher volume house condition, and posting a 300 with it a little bit back. I started with the Prime, which I had to move in about 3 & 2 with my feet/mark, to keep the ball holding pocket, compared to the Physix. All I could say was WOW! The Prime read the pattern perfectly for two games, posting a 279 and 245 without moving my feet. Then game 3, 168. I stayed in one spot WAY too long, and by the time I moved, I was playing catch up the rest of the game which turned into Splitsville. The next set I threw the Prime, I learned from my previous mistake of staying put. I decided to gradually move in with it as the 3 game set went on, shooting 258, 237, 278 for a 773. What I learned about the Prime, is that this ball will be a beast for me when I can use it in PBA where we move every game, and generally donít see as much traffic  as the right side of the lane gets. When bowling on high traffic conditions, know when to move with it, or just put it away and grab something else. The Prime also rolled great for me on the 2012 PBA Detroit Open pattern that is 42 feet long, with total volume of 25.5ml. I was able to stay put for three games on this pattern, and not see that huge breakdown at the breakpoint like I saw on the league condition, posting blocks of 673, 653, and 664, on the fairly flat sport pattern. I polished the Prime with Storm step #1 to see how it rolled with less surface, and it looks great on USBC White pattern #2.

In summary, the Crux Prime has a very unique ball motion. It takes changes to the cover very well, and doesnít seem to lane shine as quick as other super strong covers can. The biggest thing with the Prime, is to know when to make a move, or when to go to a different ball. The motion that it makes can sometimes trick a bowler into thinking they can stay in one spot longer, then they really should. This will be a great ball for bowlers who watch what is going on with the lanes throughout the night, but could possibly mislead a bowler who isnít watching for transition. Thank you for taking the time to read my review of the Crux Prime. As always, bowl up a Storm!

Storm Crux Prime

Layout: 55 x 4 5/8 x 55

The Crux Prime has surprised me, in that it has become of my favorite bowling balls that I have thrown in years. I did not expect this super strong high end ball to be as usable at it is. I did hit the ball lightly with some polish before using it, so that I could mimic the lane shine that would usually show up after 20-30 games. My intent with doing this was to conserve the energy through the front part of the lane better, which it did. This ball is still quite strong, even with the surface adjustment, but I have no qualms with moving left and circling the lane a bit when the lanes break down. Having said that Ė this ball is in no way at home on drier lanes, but as long as there is some oil in the front part of the lane, this ball is a treat. Out of box it could handle the heaviest of heavy oils. The midlane traction is very strong, but the ball continues through the pins very well. Amazing ball on anything medium oil or heavier!

The new Crux Prime by Storm picked up right where the Alpha Crux left off giving Storm that dominate asymmetrical ball at the top of their line.  Having never thrown the Alpha Crux or Sure Lock, I choose to Compare it too the Roto Idol Solid, the Crux Prime actually gives me a similar motion as Idol but in a stronger motion. If you loved any of the Cruxís and especially the Alpha Crux, you will absolutely love this ball.

Catalyst core, need I say more?? Since you asked.. If you need a ball for heavy oil, don't bother looking any further. I have never thrown a ball that literally just never stops. The deeper inside I get the better the ball reacts. I drilled mine pin up as anything drilled pin down for me is too strong on your THS. My first look with this on a sport pattern was nothing short of amazing. It allowed me to throw the ball more comfortably and not feel the need to manipulate ball roll with my hand or speed quite as much. Having a low/medium rev rate, manipulating the ball roll with such things is something I have grown accustomed to, so this was a nice change. Knowing how long the Crux Prime will be able to remain in my bag do to the new SPEC cover technology I am extremely excited, it's just an added bonus. Definitely a great fresh heavy oil ball for when my Physix just isn't quite enough.

The Prime has the brand new SPEC solid cover wrapped around the Catalyst core. I have drilled 2 and I LOVE them both. The first was a pin up 50 x 5.5 x 30. This ball is super slow off the friction which makes it very readable and predictable. I didnít think a ball this slow would carry so well, but it does. I have thrown it on all kinds of patterns except super short and it looks good on almost everything.

With as controllable and slow as my pin up is, I decided to drill a low flare 90 x 2 x 55. Normally, I only throw these layouts on short, hooking sport patterns to control the lane, much like urethane. This one is good in that setting but also handles hooking house patterns pretty well too.

If you are in the market for a amazingly smooth, controllable piece, give this one a try! If you want an angular, downlane hook monster, this probably isnít the ball. If that is what you want, give the Physix a try.

Layout: 25 x 5 x 40
My PAP: 4 7/8Ē x 3/4Ē up
Axis Tilt: Between 3 and 8 degrees
High Track Player

Intent for this ball/layout: Wanted a strong midlane read that also blended out the backend from ver reacting but still with plenty of energy and angle into the pins.

What I got: I was not disappointed. This ball motion is STONG and will read in the heaviest of oil patterns. When it exits the pattern it doesnít run out of gas like most big asym solids. The new Spec cover stock really helps this ball continue through the pins.
ē   House Shot: The fresh cover is STRONG. And in my opinion need to be adjusted to play on your typical house shot. This thing needs oil, so if your intent is to use it in league then you will need to bring the cover up to at least 3000 to account for the lighter volume house condition.
ē   2019 PBA 41ft Marshall Holman oil: The heavier volume pattern is what I originally wanted this ball for and it did not let me down. I was able to move right into the track area and the balls strong cover and core read the midlane beautifully creating the exact shape that I needed for this pattern. Once the pattern started to break down I was able to move left with it and it not run out of gas as long as there was oil in the heads to keep it from hooking too early.
Get this ball in your bag ASAP. You will not be disappointed. Bowl up a storm! #StormNation

The new Crux Prime with the Spec cover is so good!! This ball has a smooth and heavy roll motion that is controllable and continues through the pins. It is a heavy oil ball that can be used on multiple patterns from medium up to heavy oil. I've used the Crux Prime in a couple tournaments and have loved the motion I have seen so far. I am a high rev, higher speed player so I like to use balls that get in to a roll sooner and the Crux Prime is perfect for it especially on flatter patterns. This ball is a must have in the bag!!

Layout 65x6x70 Went for smooth reaction, was not disapointed
Bran New Spec cover with the tested Catalyst Core

The Crux Prime is a very stong asymetrical bowling ball. I like to use it on higher volume patterns for tournament play or on a fresh house shot.
This ball reads the front part ofthe lane very quickly meaning you will more than likey want to open your angles when throwing this ball. Slightly more front to back than my phyix.
But overall smoother than the physix. This ball compliments The Phase 2 quite well as a 1,2 punch combonation
overall perfect peice to the bag if you are missing a soild asymetrical ball.
