I'm going on a year an a half on mine now. Fairly aggressive use (Would not want them on an Enduro!)
I hear you on the multiple bleeds. I do feel that mine are slightly improving with each bleed, though, which does help ease my original skepticism... Maybe the Pistons needed to be "excersized"...?
Overall now, after my initial nonplussed experience, I do like the modulation and mid range power, but real hard grabs and brute power are not an attribute here.
I still get the occassional "gobble of death" resonance. My pads are not contaminated either. Atleast it doesn't happen everytime.
Anyone know an average weight for a front and rear lever/hose/caliper/pads?
