Sorry Katharine, I was asleep at the wheel! I think my sit bones are in between 145 and the next width up. The saddles I picked were both wider and narrower than what I have ridden before. I was really looking to find a saddle with a later "flare" and skinnier nose - so hard to visualize from pictures. I do think that 10 days is long enough to try out the saddles. some of them I just looked at and felt - and said, nope too much like what I already have had. Being able to feel the padding and compare the saddles directly to the shape of what I have used already was really useful.I was able to do a 3 hour endurance ride and a 1.5 hour climbing ride. That pretty much covers the necessary comfort duties of a saddle - longer duration and climbing - that can make or break my butt's happiness. My new saddle should be here tomorrow, and the demo selection I picked out is at a friend's tonight and tomorrow so she can try them out before I send them back. Yes, I called the phone #, but they also have a web site. http://pronetcycling.com/about.htm Curiously, their website does not clearly show their selection of women's saddles. I recommend calling them. the woman who answers the phone was very friendly and helpful. Tokie
