magura gustav man right here. i have had hopes, avids, shimano and hayes. the best breaks i ever owned were 5 year old magura gustavs. change the pads every once in a while and well......uhhhhh that was all i ever did to them. i bought them used and used them through the life of 2 dh frames before one finally crapped out on me after a nasty spill housed em onto a big rock. it was an impact no break would have survived.
