firt time i ever bought a storm ball. I always used ebonite or columbia. anyway my avg is 202, fast ball speed medium to high revs. I bowl on wood lanes medium oil with alot of carry down. the ball is 16lbs, 2 1/2'' pin, pin is slightly to the right and below ring finger, with the cg kicked out to about 3 o clock. balabce hole on my pap, rad mark below and to the right of thumb hole. now for the bowling. used it right out of the box, i hated the ball, hooked early, lost energy, didnt have a good roll to it. back to the pro shop, shined it up and what a different ball. I can play almost anywhere on the lane and the comes back. I can swing it to the gutter and it comes back, play in the middle and belly it out a little....it comes back. on my first night i shot 615, not great but it was because i was missing spares. left 2 tens entire night. i give this ball a solid 9. stronger ball than my aggression, better hitting than icon 300.
