OK, so which are the lightest/nicest? I don't care about looks. I am guessing the weight from lightest to heaviest is:
Wabi
Mavic Open Pros
Mavic CXP-22
Mavic CXP-33
Deep V's

So if you were shopping for a new wheelset today for a single-speed, which would you choose?

To answer BFloyd's question - I believe all of the other wheelsets have formula flip-flop hubs that have a freewheel built in on one side.
