I've got a pair of Ambrosio Excellight on Novatec hubs which I really like, which are probably quite similar to the Open Pro. I particularly like the machined braking surface which gives really smooth braking and still looks new after 2,500+ miles. (Pictured new, mind...)

If I was to get another pair of wheels now I would be tempted with the wider rims, and probably the H Son TB14 as suggested above.
