I have some 3 y/o Reynolds Ultra-Race which are close relatives (Very light indeed) and they've proven to be very good, light, aero and fast. Tough enough for my 90kgs on hard Michelin Pro-races.
Only gripe is that in really heavy rain water does seem to get to the rear bearings, being sealed types they take a bit of getting out compared to cup and cone. My LBS replaced a bearing for £12 all in, so not too bad.
The fronts are still turbine smooth.
The recessed spoke needs a special tool as found with those little socket sets for a few quid and the braking area metal thickness might be quite thin (weight saving comes at a price), but overall I'm very pleased with mine. They fair zip along!
