I read somewhere on basic bike fit tips that narrower saddles can be more comfortable especially for longer rides. I believe the reasoning was something like it interfered less with natural hip movement.

I've put a couple hundred miles more on this saddle since my first post and I still just shake my head at how comfortable it is. Literally no discomfort after hours and hours of riding on it. It is about the same weight as a non carbon railed Toupe which is a bonus.
