My experience so far w/ the B17 is it felt comfortable after those first very weird 20 minutes. I've ridden it daily for almost 2 years and did one century (my first & only thus far), its still feeling great. In fact, given a chance, I get downright gushy about that saddle.

Side note: On that century, out of a couple hundred riders, I seemed to be the only one who was riding a Brooks. Lots of riders admired & complimented the saddle. But it left me wondering if those numbers say anything besides "marketing forces"?
