there was a poster somewhere on the forum a couple days back trying to decide between low end carbon and high end aluminum I think primarily within the Felt line. check out this bike from Pinarello. a fellow racer has this model from a few years back and absolutely raves about it. for $2200 that's a lot of bike!
