And the best feeling, or lack there of, is when you finally get saddle height, angle, and rail position set. Then it's just incredible. I probably made 4 or 5 adjustments before I got mine (B-17 Champion Special) in the right place. It hasn't moved since.
I ride mine every day in and from work. No chamois, nothing. I don't need one. It fits me that well.
If you liked it on the first try, by and far you'll stick with it. Very few people stop liking them.
