I found, on mine, that adjusting the surface with grit (2000 for me) made the ball much more controllable in the mid-lane, and increased it's backend move because it read the lane better. In its out of box finish, it went a bit too long on oil and sometimes missed the backend reaction. So, Ric's advice to try it both ways is a good idea. Sometimes a little scuff can tame down the backend look. Sometimes it can make the ball read better, thus increasing it's ability to move more on the back. Same goes for polishing. Sometimes it can make a ball skid more and store energy for a stronger backend. Sometimes polish can make it skid right through the breakpoint making it ineffective on the backends. Depends on the conditions and what ball your trying to match up to that condition.
