Here's where I'm at. I tried again today, and still can't track. Monday, i'll have a new set of blades, a new set of blade grips, all new bearings for the grips, and new dampers. I'll try the new blades before changing anything else. If that doesn't work, i'll change out the grips, bearings and dampers. If that doesn't work, i'll order a new head. If that doesn't work, does anyone want a good deal on a lightly used SE with just one crash?
