Another Brooks B17 devotee here. I have had my butt on lots of different saddles of different types and styles, but Brooks B17 and Brooks Champion Special are the two I will *always* ride from now on.
If you aren't sure, buy a B17 from Wallingford Bicycle Parts (
http://www.wallbike.com). If you don't like it, he'll take it back any time in the first six months.
