Well, Hmmmmm.
As an owner of two VGs I can say it is one of the hardest and fastest Revving up balls I have ever seen or owned.
Mine revvs up so fast and hard! Are we even buying balls like that any more?
The tendancy seems to be going away a little from so much midlane to sort of less rev, less jump more smooth rev and smoothness.
For example the Urethanes often used particularly on the left on tour. Yet also by some of the righties too!
Another example is the strong coverstocked Super Soniq. This is really a super ball that doesn't seem to have such an incredibly hard spin up rate like the VG. But a great ball for sure on a house shot!
However, in this genre of rapid spin up Assyms like the VG, I have seen none more similar and awesome on Big oil than the RipD series by HAmmer on close-out now for obsene prices. The RipD solid seems very similar if not a little stronger than the VG(newer coverstocks).
I saw Sandra Gongora of the WPBA use that monster at the Woman's US open last year where for a portion of a block she looked unstoppable on a pattern pretty squishy and slippery at the break point where she had such a free arm with this ball it looked liked a 300 was in jeapardy every game! (knowing she couldn't overshoot the break point with this beast)!
Very similar in the Storm line to the is the available but I think expensive, is the Alpha Crux.
As to the Crux Prime, Superb ball for today's conditions. IT seems a little less rapid spinning in its rev up, it has a big readable bow and lots of area created on house conditions due to the new style of slightly slower response to friction than the above listed Alpha Crux or the RipD Solid. Watch and adjust for carrydown to appear and you can kill with that ball (Crux Prime)also!
Enjoy!
Sincerely,
