Carbon rims wear?

Im in doubt between h3 full carbon tubulars or clinchers (alu rims). Im interested to train with its. Do you think the carbon brake surfaces wear with the use. Obviously using cork pads.

Thanks

Hmmm, TRAINING wheels. Do yourself a favor -

For less than $600 any number of wheelbuilders (I recommend Ron Ruff, White Mountain Cycles) can build you a beautiful set of wheels.

I just bought a set of tubies: White H2s, Velocity Escape rims, Sapim spokes. These are beautiful, strong everyday wheels which should last a very (very) long time. What else do you need.
