Subscribed as I have the same problem. So far have been through: original specialized saddle (too soft), Specialized Avatar 155 (sit bone pain, chaffing) , Brooks B17N (same) , Bontrager RL 155 (same). Currently riding a Kontact Saddle (kontactbike.com). I really like the shape as it has a drastic leg "cut in" between the rear of the seat and the nose but I think it is going to be too narrow. Getting a pro fit done next week. Dscott, thanks for the link, they made some good recommendations. Good luck OP, post if you find a fix!
