no more drag created by thick dust collecting inside the pads, super easy to adjust pads spacing to the rotor, can now hang my bike upside with no air bubble moving into the hydraulic lines, easy trail side maintenance and best of all, I have just as much braking power as I had before... this is a tryout run with the cheap Tektro calipers and when the pads go dead, I'd like to replace with Paul Klamper calipers but they are crazy expensive, more so than top Formula, Trickstuff or Magura's offerings... only downside is the fact that thin rotors are too flexy for this type of calipers, the thicker the rotor, the better mechanical calipers will work... my Magura rotors are thicker and stiffer than most rotors out there but I've seen new rotor offerings that will be even thicker...
