Ive also read a few threads where people drilled their seat...Ive not read anything saying it made a big difference but if i were looking for the least expensive possible fix i'd give it a shotI bought the quadtech with the +1 foam and it is real nice. Also over on the other site there is an article where some folks have taken the stock cover off and drilled some holes in the seat foam to soften it up some.
That gives you a couple of options one is pretty cheap the other is not so cheap. Either way I am sure the seat is will be more comfortable when you are finished. The stock seat is like sitting on a board.
