I had a Suzuki gel seat and thought it wasn't as comfortable as the stock seat. I sold it to a fellow in Indiana who apparently likes it. Maybe he'll chime in here with his views.
I now have a Corbin and while I've only ridden about 100 miles on a warm day recently it seems a lot better than the stock seat. Bear in mind that I weigh 340 and am 5'11" tall.
I had Corbin make my Gunfighter & Lady with heavy duty vinyl seating panels vs. the leather they usually use - mostly to avoid the care a leather seat requires.
I'll be able to tell more as soon as I can take a longer ride, like a 500-600 mile day, but that won't be for a couple of months here in MN.
