Ive been through several. And for some reason a Bontrager race saddle seems to be my favorite so far. Im not sure the model name, it was around $70 or so at the lbs. Before that it was an old trek oem seat I had laying around.
The Bontrager is very firm but fits my rear just right and supports in the right places. They have a "try it and see if you like it" policy so I tried a few, and settled on this one.
I'm thinking of finally replacing the og seatpost... Could probably lose a good bit of weight.
