I read the first post and saw you are already at 245mm, so yeah - not minimal. I was thinking going from 210 to 245 or 265. Droop is part of it, but I was talking more the physics of chain tension and traction. I will put together a few crude paint diagrams or something when I get off work to explain this; it's a kind of cool quirk of bike design. Scary amount of rebound isn't good. Too much rebound (packing down), or too little (pogo stick/trials bike fork feeling)? I seem to remember whodatschrome being a pretty light guy. .58 may not be out of line, and there are some real benefits to controlling the suspension with the damping and softer springs if you can get the basic sag set correctly.
