The LBS talked me into trying a "padded" saddle - A Specialized Milano. This plastic split-tail has heaps of confectioners' sugar style foam on top with a thin plastic cover. You know what? It's comfortable! Despite all the negative press I've seen on these forums about padded or gel saddles, this puppy isn't bad! On the plus side:
1. The saddle rails are long so that I can slide the saddle back enough in the seat post
(Not the case with my Brooks B-17)
2. The wide, split rear on the saddle seems to match my sit bones fine
(When I slid back on the Brooks, I was sitting on that hard rear rail)
3. The "well" in the center of the saddle seems to get the pressure off of my perineum
(On the Brooks, the perineum was always "on the ridge" of the saddle)
On the minus side:
1. Forget about "sliding around." On this saddle, you get off if you want to move forward or back.
Overall, an inexpensive, but comfortable saddle. I've so far been able to do do my daily rides without any soreness at all. I'll try a 40-miler tomorrow & let y'all know.
With such good results so far, I'm thinking of trying the Specialized gel saddles with the "body geometry" spacings. I tried one once before, but I think it wasn't really my size.
So far, I like the Specialized Milano better than my B-17! Time will tell if initial impressions will hold up.
