Okay, so Performance has these on sale (today only) for $280 for the set. My original intent was to wait until I could afford to have a set of HED C2s built with something like DT Swiss 240 hubs, but I'm tempted.
My main wheels right now are Open Pro CDs with a PT rear and an Ultegra front hub. The Eastons would be my race wheels, I don't need another set of training wheels. Would the Eastons be a noticeable improvement (aside from the ~400 gram weight reduction) over the OPs?
