If you like the LBS tell them "Don't sell me WSD because I am a woman. I want what fits!" I am 5'2" and like WSD due to a shorter torso, some women do not have a really short torso like me and the standard top tube length is not a big issue. My mountain bike is WSD but I got it off craigslist. It has not been professionally fitted. It works for me though.
