Sorry for possibly bringing this thing back from the dead, but I recently installed some TRP CX-9s on my new bike, and WOW. Great modulation. I can feather as light as I like, but I can also keep going and without a supreme amount of effort (from the hoods) I can lock up the rear wheel or scare myself with the front. I can finally break strongly with my left hand while downshifting with my right. These are exactly what I was looking for with disc brakes. They do diminish a bit in the rain, but they are always powerful. And they don't make a sound. The pads are about 2 mm from the rim, so I had better keep my wheel super true, but other than that they are great.
