WSD bikes don't work for me at all. As Torrilin said, they are made with the assumption that women are proportionately longer in the legs and short in the torso, which is true for a lot of women. I'm not - I've got long arms and a long torso, and the women's models are all wrong for me. Which is kinda too bad, since a lot of them really appeal to me aesthetically. Ah well!

Your best bet would be to find a really good bike shop that's willing to take the time to figure out what you need - or even better, schedule a formal fitting.
