The solid winner among the high mileage women I know was the Selle Italia Trans Am women's (Lady) model, now out of production for about two years. I'm looking for one for the back of a tandem. Selle Italia did replace it with a new model (Gelflow?), but I haven't seen anybody using it so I can't comment on it. I believe both the new one and the old one are built on a shell with a wider and shorter profile designed especially for women. All the women I know who use the old one say it is the best saddle they have ever had, this in spite of heights between 5'2" and 5'11", which you would think would have had some effect on preferences.
I'll be out by Cleburne this Saturday morning with a group, 0700 start, doing laps past Cleburne State Park and the lime kiln, on Park Road 21 (?). I'm bringing my pepper spray in case I have to hose the dogs on FM 1434, but likely they still remember getting too close to the nice woman cyclist last week, and they won't come out for anybody, even (doggie) value-menu-sized guys.....
