I have Performance CF bars on one bike, and FSA Wing Pros (Al) on another, and honestly, being a clyde, the additional flex of the CF bars take a little getting used to. Your choice of tires, wheels, and fork all conribute to the amount of buzz you'll feel at the handlebar. On a price/gram scale, Al wins hands down. Something like a Deda 215 bar would be a worthy upgrade. Or you could do what Treespeed says and get wider tires. Cheaper option, would make a noticeable difference.
