If you look at the Geometry of the Trek 7.2s for 2008, you will find that the WSD and the men's are the same. When I purchased mine in Oct. I pointed it out to the salesperson. He was pretty surprised. The 7.3s and up do have a difference, it was just the 7.2. I had a 7.2fx wsd like Zen's which I sold, and regretted (black with pink writing, very pretty) and in Oct. I purchased the men's 7.2fx which rides exactly like the wsd one did! It was in a mocha duotone which I loved. I didn't care for the women's baby blue. It's on the trek website. It's a brown.
Try riding both kinds and see what you think.
