To elaborate, the comfort seat i was using has about a half inch of gel with about another half inch of foam under that, and the stock breezer seat has about a half inch of a higher density material that "dents in" where your sit bones rest to keep you from shifting, bt soft enough to be comfy on longer and rougher rides. For real the first 2-3 weeks with the new seat was really uncomfortable, but my body i guess got used to it or the material wore in or something, but i swear it seems more comfortable than the old serfas gel comfort seat....
I had the TB40C, but i think you may want to look at a trimmer model.
