The complaint (from me at least) is that by the time you get the levers tight enough that you don't worry about them moving the feel is lost. I don't think they (Campag.) thought about it enough.
My current favorite is a Suntour ratchet barcon shifting a Cyclone GT derailleur with one broken spring. Talk about a light action! Disclaimer: Works swell on five and six speed freewheels; high gear on a seven speed was less certain. (the low spring tension requires cable and derailleur be kept clean.)
