I looked at those for my bike, and I looked again for this thread, and I still couldn't see what advantage they had over Kinlin apart from snobbishness.
The vs are a sort-of domed profile, similar to an Archetype. The clinchers are really stiff (I've no experience of the tubular version). They've no flat or machined braking surface, which might be desirable for track wheels (unless you want to ride to the track).
There are still some super classy NOS campag Omega box section and V.
