My biggest hangup with buying CF in general is that, while it's not fragile, it's not really super durable either- a ding that would just put a nice "personality mark" in a steel frame will be (if you talk to most of the people on here) a death knell for a CF bike.

I don't know about you, but all of my steel bikes have dents in them, so I've stayed away. If you've got the coin, they seem to be the best, but I sure am not gonna risk it.
