CF is fine. You'll love it. I have commuted for years on steel, aluminum, CF.
AL was stiff but fast
Steel was noodly, not light, but comfy
Cf is stiff, light, comfy. Weight helps with hills and stop and go. I like the comfort and responsiveness. If its your desire, you'll love it.

I only worry about chipping and abrasion when strapping it on a bike rack on the rear of a car.
