Familiarity: I've put it through the wringer
Having replaced Avids with these, Shimano once again proves XT to be $ for $ the best value and performance one can buy. These things are the bomb. They have greater power, articulation, and tool free adjustability than any Avid, Magura, or Formula brake I have used.
