I have a little shudder in front and I'll try the more toe in. I've also had the problem where the stud is a hair too short and the fixing bolt causes the Tektro CR720 brake arm to bind a little. Of course, that's on a non-Rivendell frame. I tell ya', I haven't yet found a high-profile brake that solves all of these isses.
