I haven't used Avid's on the road but I have tried a few non Shimano rotors and didn't like how loud they were. I've had to order SRAM Centerline's which are not cheap. I would rather use XT or Ice Tech Shimano rotors (which are also readily available in LBS) but they are not available at 140mm in 6-bolt.
