AJ,
so far all the listed check out, allthough I'm not sure how main shaft bearings would mess with blade tracking ^^;. I think I might splurge and go get a new set of non-plastic blades, see if it helps, I'm wondering if maybe I've finally gotten the head speed to high for the plastic ones (I've slowly been increasing head speed as I get more and more comfortable with the extra control)??? THats pretty much my last idea though. Guys thanks very much for all the help and suggestions, I'm sure I'll be back soon enough to complain about soemthing else
