I am in the 225lbs range and run the Sintered front and rear. I find the modulation excellent and the power plentiful. The T100 Sintered may require a bit more fine tuning to keep quiet but well worth it. I run another brands 220 Rotor, hoping Hayes comes out with their own 220 rotor and Post Mount.
Love the lever action, modulation, and power of the A4 Dominions!
Semi-met are great but don't last as long as sintered. Hard to choose between the two, I think I like semi-met better.
Second set of pads on my A4s. I got great life out of the first set. Love how quiet yet effective they are.
I love these brakes.
