I would also consider ADDING surface to the ball as opposed to polishing. Adding surface can help the ball expend some of its energy earlier on the lane so that the back end stays smooth and controllable. We have a guy in my house with a slow speed and a lot of hand, and he uses 500 grit (or lower) on his Asylum. The surface helps tame the ball down, and his hand still gives it enough to get back up the hill and hit with authority. I did something similar when bowling two-handed. I had a Hyroad that went sideways with the box finish, so I always kept it at a fresh 2000. The ball still had plenty of pop, but it blended the reaction out a great deal.
