Just an update...
Had my BWB polished and so far I like the results. Goes longer and snaps hard. Is more skid-flippy, which I realize is a bad thing in some folks eyes, but that is what I expected when I bought this ball.
It now saves a lot more of it's energy and seems to require less effort to throw. Before it would alternately burn up before reaching the pins or slide past it's intended breakpoint when a little too much speed was added. Is much more controllable now in terms of how angular it is from shot to shot and how predictable it's path is. Bowled an effortless 244 and a 245 with it in it's polished state tonight. In it's OOB finish, had a few games over 260 (including a 289), but way too many stinkers along with those.
Only thing that concerns me, is that it can't handle quite as much oil. stronger than the Anger. But until I polished it, it didn't really have a niche in my arsenal. Burned up too fast for medium oil, went to long on heavy oil. Now.... it kind of fits nicely between my Anger and my Ebonite Raid. Deeper than the Anger and a smidgen earlier than the Raid, with a somewhat more skid-flip reaction than either of those two balls.
So far... I am happy with the results of ths experiment.
