I had 2 pairs of Ones, the first gen and second gen and I didn't think brakes could get any better but the RO's I currently have are phenomenal. Not a single problem, and certainly no noise as others described. I had a pair of Saints on a bike for a short time but I always felt like they were either on or off, no in between. I've been running Formulas since 2007 and don't see myself switching to anything else until I have a reason to. I am curious to try the new Saints though...
