I have one now, and I like it a lot. It's a very versatile ball. I start out with this ball when the heads are fresh (I bowl on synthetics, medium to medium-oily house shot) but I don't have to immediately put it up when the head oil starts to go. It's opened up 5-10 boards on the approach I didn't have before. Nice arc with some boom in the back and it doesn't hit weak. The heads have to be completely blistered before I have to step to something else.
I wish I could compare it to something for you, but the last Storm ball I had drilled before this one was an X-factor about a month after that ball was initially released. That was two pounds of ball weight and about 500 games ago, so giving you a comparison wouldn't be fair to either ball.
