I have the EX 9.0 with the Juicy 7s and they squeak and squeal. I put up with it but my friend got so disgusted with hers she sold them on CL. She was at the Avid booth at Sea otter last year and they swapped out pads, rotors, to no avail. Gobble gobble and rotors always seemed to be...off. I quieted mine some by sanding the pads with super fine paper to take off some of the sheen.
