As someone very late to this guess-a-thon party, I too noticed the carbon/alloy combo--mostly because I have the same thing going on for one of my bikes. Record shifter body that I rebuilt the back halves to, with brake lever 'blades' from a busted Chorus Ergo set (hoods, too) that I had thrown into a Campy wheel buy over a year ago. Essentially free is good. Campy brake lever blades are stupid expensive and it baffles me that there is absolutely no middle ground price-wise, to say nothing of availability. I would be happy to pay $20-30 for a no-name set in black (just to match).
