Jonah,
Keep the ball as clean as possible to retain the original reaction. I would not change the surface at all. Why mess with a good thing. I still have mine in the box, will punch it out tonight. I was told by amateur staffer Paul Bober from Morton Grove Il (Chicago's Bowlers Shop), that it was an awesome ball. I already punched out the Bedlam, which the way I drilled it, will destroy house conditions.
