Need some advice. Does it do any good and is it worthwhile to add surface to a plastic ball? One of my teammates, a lefty, uses a plastic ball (an old "soccer ball", his only ball) in our men's league, and for the last several years has averaged in the mid 190s with it, able to hook the ball with a nice down and in shot. This year, the shot they put out is now heavier and a little flatter, and he has been struggling, especially the last few weeks because he can't get the ball to turn enough. Our 3 weeks of roll-offs started last night, and the problem was way worse, as he shot 145, 143, 136. If the lanes are the same next week, would he see any improvement if we took a scotch-brite to the ball during practice to add surface?
