There is another thread up right now that asks a similar question. I have a used B-17 in a box at home that I can't wait to try, and maybe I'll be as bowled over as so many have; but the most comfortable all-day saddle that I have used is the WTB Pure V. I had a touring bike that I didn't like the saddle on, so I took the Pure V off my MTB and was surprised how many other touring bikes I saw using the same one.
