I like the Brooks for looks and for shortish rides. It's a lovely saddle but I wouldn't do a century on it at this point because it's too firm (although I DO like the shape). No cutout, though.
I live near an LBS that sells Bontrager saddles....I may check out the Affinity if they honor the 30 day return policy. If not, I may just go back to the Jett. Although it's definately not "the one", it's the best one I've had so far and I know I can ride a century on it. I'd put my old Jett back on, but somehow one of the rails got bent and now it's ruined! The Arrowhead is up for sale, BTW. PM me if interested.
