A great bike for a seriously competitive racer - perhaps the most bang for the buck you can get without talking a big risk - but are you in this category? If not, a Kona Jake or Specialized Tricross will be 99% fast (probably faster than the CAAD up hills when you're on the heavy side of one your swings if you get a triple) and solve that ride problem the only way that really works - by letting you run wider tyres. Racing bikes are designed to let highly athletic and flexible 150lb riders move fast, not carry ones approaching 300lbs in reasonable comfort. You could also save some space, because you wouldn't need the Kona PHD anymore.
