organic pads simply do not work well for me. they are rapidly eroded by the huge amount of wet grit i encounter on my daily descents. in fact, one of the reasons i upgraded to XTs was that they are designed to work with metallic and/or sintered pads. i switched to cheap taiwanese pads over a decade ago and i currentlly have half a dozen semi-metallic serfas pads i bought for $8 each.

note: using metallic pads with some disc brakes can result in failure.
