Another vote for Vince's blue discs. I can get several bowls from one set of discs. As for the Abranet, I have little experience with it. I did try some once, and with the coarser grits, they didn't cut as fast as the standard blue discs from Vince. At about 220, that difference goes away. I have been searching for over sized cubitron discs from 3M. Mike Mahoney told me they exist....
