You should try Spyres or Spykes.
After too many hassles with my XTs, I bought a set of Spykes recently. The bearings in the lever arm felt like they were made of sand. Did not even mount them, I sent them back. Maybe these were a fluke, and I have suspicions that they may not have been legit (there are a bunch on ebay for ~60% or normal price, no original packaging.... hmm).
I've read mixed reviews on them. A few people mention that the pad adjuster knobs do not stay put without locktite (which makes them hard to adjust). Sounds like these are great when they work, though.
