I am a short a#se (5'7" with dinky little legs to match) and bought a low seat with the bike October 2004. I have found the standard seat to be far more comfortable and no problem. I have had 2cms added to the heels and 1cm to the sole of my boots, helps a lot.
A good cobbler can easily do the job, and as long as orthopedic rubber is used, the weight penalty is minimum.
The low seat is shaped like a banana and for me uncomfortable, both through lack of padding and the tendency for it to make me slide forward into the back of the tank. So I wish I had not bought it.
Then I had an "idea", always worrying that.
I took the cover off the rear of the low seat, chopped the low foam down with a bread knife, took a bit off the plastic base with an angle grinder and stapled the cover back on. Now it has a much flatter profile, and with an air hawk seat thing is extremely comfortable for long distance touring. Looks pants but works very well. The combination being no higher than the standard seat on low setting.
Most of the above has little to do with the original thread, but am I bovered?
