I went into a specialized dealer thinking that I would buy a 155 jett (since the 143 felt just a bit too narrow) but a helpful associate pointed out that the jett (and maybe some others of their saddles) have rounded edges, effectively narrowing the saddle. She pointed out that the ariel has sharper "corners" and suggested I try it in a 143. Sure enough, it was much more comfortable and really felt like it supported my sit bones. Just something to consider.

Regarding the bontrager saddles: I heard from a friend from a friend (etc through the madison biking grapevine) that bontrager's saddles were not built to spec and the womens saddles essentially came out as men's. And they are again redoing them for next year. So I would avoid those.
