Lucky,
I am really surprised that you polished yours up to 1000 grit. I have two. One drilled 5.5x 4.5, pin over the bridge. It's my "lanes dryin' up and gettin' spotty....save me" ball! And the other polished to about 800...4x4. Gives a nice strong turn at the breakpoint, and I can use it on some mediums.
But the #1 ball, with the early roll drill, is rather scuffed. Very little polish, yet it gets me outta jams time and again. Has a slow continuous move on the backend, but just rips the rack, flush or lite!! Got to be one of Roto's all time best balls.
Whenever I have too much polish on either of these balls, I either ping 10-pins or ping 7-pins.
