I did the search thing. Didn't get much satisfaction there. I tried to register over at the fearful board but I guess I was too slow or the man over there was a little quick on the trigger deleting my application. In either case that's a little more overhead than I need for one answer so, I'm asking you guys. I use Acmes, I love Acmes. I'd love them a little more if they had a little less low, low, low and a little more efficiency. I get the sense that Fearful will do all that while still retaining the honesty from 50hz up. Getting 20 or so pounds off the lift wouldn't be a half bad byproduct either. So...educate me. The comparison to the B4 is my main interest as opposed to the B2 or 12" boxes.
