Earlier this year, I began a demo with the Specialized saddles. To date I've fit about 50 women on the Jett and the Alias (essentially the same saddles but the contours of the cut-outs are slightly different). I've personally been riding the Toupe 130 for the past 1,000 miles or so and I love it.

All the specialized saddles feel a bit firm on the sit bones when you first ride them. I didn't find this uncomfortable, just different, but I ride very tilted forward on my soft tissue (not back on my sit bones).

The more upright you sit on your saddle, the wider a saddle Specialized recommends. I'd say you should try the 155.

Another thought about saddles is that the more frequently you ride, the sooner your body will adapt to the new feel.

Hope this helps!

ps -- to get a truly accurate measurement of your sit bones, you should place your feet up on a 12-18" high surface (ie an ottoman or a footstool works well).
