My take:

CCB Pros

• Reduced unsprung mass
• Will likely outlive the car if not driven on track
• Less brake dust
• They look nice
• Improved brake feel (when dry)
• Better fade resistance than iron rotors with stock pads

CCB Cons

• Expensive to purchase
• Do not provide shorter braking distance than stock irons (prior fade)
• Do not offer better fade resistance than irons with track pads
• Will wear just as fast as irons with track use
• Very expensive to replace (see previous point)
• Are more fragile to manipulate (see previous point)
• Can be more noisy
• Offer less initial bite when wet
