If any of you nice folks have personal experience with riding on a Selle Anatomica X saddle and a Brooks Cambium C17 saddle, would you tell me which one you preferred and which was the most comfortable? I have a Brooks B17 on my bike right now and it is getting better, but far from comfortable at this point. I will ride the B17 until my butt falls off, but I would like to be prepared for a plan B. Thanks!
