These are the wheels I built up for just such purposes:

very similar to an ultregra/open pro - but swapped out the Ulegra hub for Campagnolo Daytona (more or less equivialent in campy's line up), and went with the Ambrosio Excellight SSC rim, which weighs in approx equal to the open pro. Still waiting for my new tires to arrive, hopefully have a full ride review of them by the end of the weekend.
