I bought these before going out to France.
I think we need to be more specific about the riding condiions we experienced out there this year. Some people had it super dry and dusty, other's not so much (me)

I went through a pair every second day, at which point they were on the metal.
They were teriffic feeling, but as soon as it got a bit wet and muddy, they got raped.
My front brake was terribly noisy, so much so I thought my rotor was loose, as it sounded like metal was being shaken rapidly.
Excellent pad feeling, very very poor life in the wet, and horrendously noisy.
I'm going back to superstar sintered for my Avid Elixr's.
ps: you can hear them in this vid... and this was at low speed, the noise eaily got to 3x that noise.
