Maybe a stupid question, but does a split in One Bowl Roll count toward the achievement if you knock it down?
Also, every time I try Pin Rush, the ball never seems to want to release from my left hand. I constantly get a bowling ball "stuck" to my left hand. I'm doing the windmill method, and my arm is clearly making a throwing motion, but the ball only gets thrown maybe 20% of the time. It's driving me crazy. Anyone else have this problem?
