mnmkpedals, I suppose that my "logic" is brand related. At this time all of my roadies, including the touring bikes, are Cannondales. Cannondale was the first frame I couldn't flex the big chain ring into the FD and their general geometry, at least through the CAAD3, fit me very well. One would think that I would also prefer a Cannondale mountain bike, but Treks have always been better fitting.
