The Crux is Storm's newest addition to the premier line. The Crux has an ERG Hybrid Reactive cover stock with a new Catalyst Core. I drilled mine very similar to my Zero Gravity, 4.5 x 4.5 x 2 or 45 x 4.5 x 35. The Crux was a too strong with the 3000 factory finish, so I applied Storm Step 2. The Cruz has a stronger ball motion than Zero, still pretty clean through fronts for an asymmetrical. But has lot more backend motion as where the Zero was pretty smooth. Plus the Crux has very good continuation through the pins. I have thrown the Crux on house shots, but only able to use it for about a game. Used it on Kegel's 45 foot RT 66 and it rolled great. Gave me the very predictable midlane roll and good continuation off of the break-point.
The Crux was a very popular choice at a couple Storm Matchmaker events. All styles of bowlers really liked the Crux.
