I played on a Predator barbox at last year's Expo for about 20 minutes. It played perfect to me, including the pockets. The only thing I didn't like was the "tink" sound the balls made when hitting the pocket.
You guys are forgetting that most players, even serious players, can't run a rack on a Valley. Easy pockets are ok imo. (And the Predator pockets are nowhere as easy as a stock Valley). Super tough pockets like on a 9' Diamond take the fun out of the game. Medium tough pockets like on a 7' Diamond (shorter shelf than the 9' with the same pocket cut) is about the max difficulty tables should be for 99% of the players, imo.
