They're using a lower-volume version of the Cheetah.  Starting with the Round of 64, everyone will use identical, unmarked plastic bowling balls with pancake weight blocks, branded only by the PBA 50th Anniversary logo.  They'll initially be given two balls, but they can drill more throughout the tournament, and they are allowed to alter surfaces on the balls.

I think people who can get the ball down the lane with moderate revs will do well since their accuracy will shine compared to the power players.  People who are good at changing their release also will have good success.  Those who tend to get the ball into a heavy roll and like to play further out (WRW, Duke) will probably be around, even if they hang a couple corner pins.  Also, I just have a hunch someone like Steve Jaros will have a good look at the pocket.

i'd like to see someone like couch do well, he's been bowling decent but not great this year

it doesn't take a massive amount of hand to get a plastic ball to turn, you cant fluff it, but you don't have to crank it either

down and in guys are going to dominate, but be prepared for a 10 pin fest

I could see PDW holding his own at this with his ability to kill the speed combined with accuracy.
