That's an excellent point and I'll be sure to inspect the ICE rotor very frequently. My initial observation on a 1000' downhill is that the ICE rotor with KoolStop metallic pads required much less pressure to develop braking action. There were no switchbacks and with the roads a bit damp I kept my speed down, but the lever pressure is definitely less than with the Avid rotors.
