If the price and fit are right I'd be hard-pressed to pick the aluminum over the carbon. I rode some pretty miserable miles in my first year on my aluminum frame. You ride a lot of the same roads I do. First 20 mile ride on carbon and I will never go back. At least not as long as I live in the land of chip-seal. I might reconsider if I lived somewhere with nothing but buttery asphalt, but that's not here.
