I'm on Shimano Saints and i just swapped out to the Green galfer pads and 2.0 rotos. they work well, performed as good as tock or better after a bike park day and the local trails. since i swapped 2 items i can't say for sure what made them work the sam e/ better than Icetech rotors and metallic pads.
Commencal in squamish stocks the Galfer x Commencal pads for a good deal on their site.
I've used stock shimano Finned metallic and the Loam Goat pads as well. loam goat was not as good as stock, but the price was right. they wore faster.
my wifes codes have had the same pads, Stock metallic , Loam Goat and now Galfer. did a rotor swap so more than pads. no turkey gobbler noise yet, but wet season is around the corner and the brakes will soon be singing the sone go their people!
i want to try the MTX pads as well, but no stock to be found.
