WSD was absolutely necessary for me. I'm 5'5", short arms, short torso. Spent all last year on a Specialized Sirrus with a 54 cm. top tube that was way too long for me. This year, went through two bike fits, one with the Fit Kit and one by an expert cyclist and physical therapist, and both came up with the same results--that I needed about a 50-51 cm. top tube. None of the guy bikes could provide that. I got a Bianchi Eros Donna and love it. Don't feel even a little squished.

It really is important to get a good bike fit done, preferably by someone who doesn't have a vested interest in selling you a particular bike, and then to test ride several different bikes. Even if you have to make a long trip to test ride, I recommend it--it's worth the time and effort to make sure you get a bike that works for you, WSD or not.
