I polished mine up since it was burning up in my house. It definately looked better and got down the lane a bit easier. Still, it was way too strong drilled 4" pin-pap. Got down the lane easier and had more pop on the backend. Works well if you like a nice controlled reaction on your THS. But in tournaments with more oil down, the polished surface was a bit too squirty in oil. The 800 grit finish is much better suited toward that kind of environment.

Bully Your Competition

this is one aggressive reactive ball. even smooth sanded very fine and highly polished it's not meant for drier lanes unless your ball speed is well above average( 22+mph ).
