I don't have much to add- what's been written already is great stuff- except this:

When I switched from a HT to a FS, it took me a long time to get used to the action of the rear suspension. Because of this, I ran the rear shock too firm, and then wondered why I felt high and "bucky" on the bike. I swear, I thought that thing was going to launch me into the nearest tree! I revisited my shock set-up, and lowered the air pressure to something more suited for my weight, which in turn allowed me to better fine-tune the rebound. All of this added up to a more "in the bike" position, a suspension that properly unloads without packing down, and more confidence. Something to try....

//is off to remove seatpost from frame like Irulan suggested...and break that bad thigh habit!
