We just rode a century with Stoker's brand new Specialized Oura Expert saddle. Total success. Stoker said the saddle "disappears." No butt or other soreness during or after. She has aero bars and has to slide back on the saddle to use them comfortably, but that's fine. Only thing is, there's less padding than her previous Lithia saddle, so I think a carbon seat post is in her future. Specialized CG-R if I can find one.
