I've had one for the last couple of weeks. I have mine drilled with the pin up and to the right of the ring about 2", cg straight down from there and a balance hole. I'm a high tracker, med-fast speed, medium revs. On most of my stuff I like to stand 25 throw to 13 at the arrows out to 8 or so at the break. With this ball I have to play up the boards a little more, I'll stand 20, to 13 at the arrows out to 10 or so and it comes back hard on the backend. On dry stuff I have to keep my speed up, or it'll come through the nose and I can usually miss it right a few boards and it will come back hard. If I miss left it will hold in the oil, but will usually hit light if that happens. This ball has a ton more drive than Storm gives it credit for. I've blown past the 9 a few times on flush hits, only to have a messenger come through and knock it out.
When I first used the ball it was a bit jumpy, but after a few games it settled down nicely. The ball breaks about 3-5feet later than other stuff I've thrown, so it did take some getting used to.
