Oh, I know. I currently have resin pads in the front. I wore a set out during TCR though (4-5000k) so for TABR, which is 6700k I'd like a set that last the whole race, hence metal. Also, less frequent changes = fewer chances for me to get angry with bike and destroy calipers in a rage.
Resin is adequate, that's for both commuting and polo duty.
