I sidehopped to my Avid caliper and a pedal in a section at the Euros.
Brake worked fine, just scratched. So they don't fall apart the moment you hit them, and the power is excellent.
Mine squeals a bit now, but will probably quiet down soon, mine has been a bit inconsistent when it comes to grab and noise; one day it's super grabby and silent, and the other day it lacks the crazy bite and squeals a bit.
Power is still really good though.
