Still searching for a reliable dry-lane ball, and I've got this Chainsaw sitting around that completely confounds me, so the choice is to use this thing or have simply a nice piece of furniture.
Surface preps tried: Box, 600 Abralon, 4000 Abralon, now it's at 1000 plus polish. That's the best so far.
Drillings: 3.75x5.25 pin over ring with CG under middle, then I added a weight hole in P3 on the NAP side of the ball. Seemed to work better with the hole.
I've found that the ball is really speed-sensitive. I really hadn't tried adjusting speed much until this week, but by slowing it down, I do get it to give me a decent read that I hadn't really seen before. But I've changed so much on this ball that I can't really tell if it was me or the changes to the ball itself.
If anyone has unlocked the code to making this thing work, I'm all ears. I'd rather not do a full plug and redrill.
