You could keep an eye out for the top of the line PSLR0 carbon wheelset which are around 1520 grams. Sometimes the house brands go pretty cheap.
ah, i was getting confused with OP's Pro 0.Advanced Pro 0 and 1 get the 1750 gram P-SL0 wheels, mine is the 2 with slightly heavier 1870 gram P-SL1 Disc wheels. Only difference I can see is thicker spokes... I could probably shave 150 grams with lightwieght aero spokes!
Im happy with them though, can treat them like CX wheels without worrying about them.

Thanks Piston - very nice, though at that price you start thinking new bike!
Looks drilled through to me...? http://www.giant-bicycles.com/en-in/gear/product/p.sl0.disc/1184/61373/P-SL1 & P-SL0 wheels use the same rim extrusions, but they're drilled differently. The 1 is not tubeless (although it has the lip on the bead seat), it's drilled right through & eyletted. The 0 is a sealed rim with alloy inserts to hold the spoke nipples.
