I recently laced up a set of Chris king r45's and some Hed Belgiums with dt aerolites on the drive side and revolutions on the non drive in rear and think this would be a great combo for a Zurich. Getting an ultralight/über stiff carbon wheel set is basically wasted money on a lemond Zurich depending on your weight. Go for durability and comfort to match the steel Zurich.....with the king/hed combo you will be dropping some noticeable weight over a stocker ultegra wheel set while possibly maximizing stiffness gains without going full carbon IMHO.
