I am at box (4000) and like the way this thing chews up the wet/dry on league patterns.
I spoke to friend with a lot higher rev rate and he said he took his down to 1000 and then polished it litely. He also put a weight hole inside his axis point deep enough to hit the core and the ball picks up strongly off the spot.
Like it has been posted before, 4000 is as close to polish as you can get with out the gloss. If you are looking for earlier, then hit it with more surface. If you are looking for late, then shine it.
