Another 6'r here. My bike is 57 cm and fits great. I have been in to my LBS to tweak the fit many many times and I would recommend buying the shop as much as the bike. Machines are a great idea, but I want to hear why an adjustment is needed and I want my fitter to listen to me. So go to a bike shop with great personal service if fit is an issue.

Second, I don't know about WSD, but the geometry is so different model to model. I found that what I read about bikes in reviews and how they felt in person was really different. So to reiterate what others have said, go test ride.


Good Luck!
