I didn't have mine polished as such. I thought the ball was more than 2000 abralon out of the box. I compared it with a Storm Double Agent, which is at a 1000 and it appeared the same. So I had it taken down to 2000 abralon, which is what is listed in the literature for the cover of this ball and..I had a 621 with it Tuesday night. If I could have converted on more than just 2 of six ten pins, and not chopped two 6-10's, I'd have been close to a 700. Hits a ton.
