I remember doing some 10 pin bowling in college and got my avg over 180. Here is a PBA bowler who uses both hands on the ball for tremendous torque to power the ball thru the pins.

It's all about spin; most pros get 400 revolutions per minute on the ball, but Belmonte can hit 630. Consequently, more energy hits the pins.
His average is 230 and he has bowled 34 perfect games (300).
