I did put polish on mine. Specifically, I took the surface to 320 on six sides before applying Brunswick Factory Finish High Gloss on six sides. I got several feet of additional length, and a more defined move at the break.

I took my evil seige down to 2000 abralon, then back to 4000 and then i polished it with some majic shine I had. It just makes the ball go longer, doesn't really flip over anymore. It might be better for burn up heads for me down the road.
