The crunch!!!! I've said it in another post, but my god this ball is awesome. Have 2 drilled up, am going to buy a case and save them. Based on the kind of bowler i am, i haven't drilled up any of their high end balls (too much ball for me, and not a huge fan of particle) but for those who need them, they are terrific. I love this ball. It reads the lanes great and i never have the problem of over under reaction. Anyone looking for the best overall resin ball on the market, get a crunch or 2, or 3.
