Ride them, I personally am not the biggest fan of my Synapse because it is not a real WSD. So it actually doesn't fit me with the top tube being too long. If you look at the geometry chart it is the same as the men's. They do put shorter cranks, smaller bars and shorter shifters, but personally I need a shorter top tube as well. So what did I learn? Know how you want the bike to feel and ride more than one. I loved the stiffness of the Cannondale so I thought it was better, longer rides quickly proved me wrong because with the wrong fit it isn't comfortable like it is supposed to be.
