How long do you spend in the saddle?

It's very hard to recommend anything besides a Brooks because saddles are the one part of a bike which is extremely personal. The one thing to try and avoid is overly padded saddles which will cause lack of blood in the entire seating area, resulting in very unpleasant numbness. The best is to go to a bike shop and try out some saddles. You need to be able to ride it for at least 30min.
