I'm hoping that during the course of my problems I actually had more than one problem, and that I've solved one of the problems already and now I'm just missing some lost wheel weights or whatever (going back for wheel balancing *again* tomorrow, which was the first thing I did in my debugging months ago).

I hadn't thought about the hubcentric rings in a long time though, so I'm glad this thread popped up and reminded me. I have plastic hubcentric rings on these Forgestars, and they've been through a lot. Maybe they're worn just a hair too much and that's contributing, and I just need to order some new plastic rings.
