echo many of the comments here – lovely brakes, powerful and much much better modulated than juicy's. More linear and less grabby. Pad replacement is a doddle. I have also had the same problem with bad factory bleed on my rear brake, but once properly bled they're great.
In the past I've run 2-pot (non-servowave) xt's, 2-pot saints (same brake), hayes, juicy's, formula oro bianco's and these are my faves. For info I weigh 11.5st and with 203/185 rotors they're plenty powerful enough for alps use on my pitch too.
If you do get some you can get cheaper bleed kits from red dog racing which work just as well as the avid ones (used both)
