You should look into a Cane Creek Thudbuster LT Seat Post, i know, i know. The Reverb is amazing however i think this could be great for a Hardtail; you still experience the hardtail experience however your seat doesn't get shoved up your ass every time you hit a bump.... Just the tip
well these cane creek 'thudbusters' are, for one very expensive, look retarded and reduce pedaling efficiency on the climbs and you're going to be standing up on the dissents anyway, so whats the point really?
