It depends...on the average league level, its a game/hobby, easy oil patterns with hook in a box bowling balls, doesn't require great ability to throw decent scores. PBA and true sport bowling, usually just grabbing another ball does not cut it. Got to match your speed and angle with the way the lanes are playing and must be able to Repeat. That takes skill. Average League night=Game, Pro Level= Sport. No one real answer.
