This ball is supposed to be a huge hooking ball, and it is, if you have enough revs on it. It's AMAZING in oil, the best ball in oil Storm has made, even better than the Trauma ER, I think. It reacts directly to the amount of revs you put on it. It has much more length than it says it does. INCREDIBLY versatile. Take some of the hand out of it, and you could run it off the gutter in virtually any condition. I was extremely surprised with it. It reacts nearly the same on dry as it does in heavy oil. A deep inside line on dry will give you a smooth arcing backend and plenty of length if you're deep enough, and just move right for oil. If nothing else can find even a board of backend on oily conditions, just slow this ball down a little, and you'll find backend. Granted, heavy oil is difficult for anything to cut through, but this ball is your best bet in that respect. I didn't do anything to the surface, just take it as is, it comes out of the box perfect. Crankers will do better than strokers, but strokers will find this ball relieving on oilier conditions. It flows right off your hand, and plays an inside line the best with the smooth arc to the backend that crushes the pins. The carry is excellent, but it tends to leave soft ten pins occasionally if it comes off your hand with less revs. Wonderful ball, in fact, I just talked myself into buying another one just writing this. I'll order one tonight!
