WSU,
I have the XXXL and it is perfect for what I bought it for, fried lanes and spares. I've practiced with this ball on a fresh shot with clean backends and I was able to play down and in with some success, but you really have to make sure you're squared up. One guy that I bowl with, who turns the hell out of the ball, can use his on medium/dry when the backs are clean. If you have a ton of hand it can be used on some mediums, but all in all it's a dry-fried ball in the hands of the average bowler. That's not to say that you can't use it on slicker conditions, but you'll really have to point it. Nevertheless, the hit is absolutely fantastic.

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
