RetroRich, I've checked into prices of new seats vs. modifying my stock seat: Ultimate=$480, saddleman=$380, SoCal gel mod to my stock seat=$200.
I actually like the stockseat, it's just a little hard, and not quite wide enough for my wife. I'll keep you guys posted, but since I'm retired, I'll try the SoCal mod first.
I have to make a revision: I found the Saddleman Explorer seat for $313 at xtremerevolution.com!
