That's a good question that I've been meaning to ask myself. I'm a fairly big guy (250 ball park and dropping) I'd like to know which model of Brooks saddle would be best for me. I'm intending to put this on my hardtail commuter bike and possibly an Raleigh Robin Hood should an appropriate candidate become availiable when I have surplus cash. I was going to ask The Fixer, but I figured I'd tag along on this thread.
