All other things being equal, Campagnolo Record or Super Record hubs make wheels fast in my experience. Of course, 105 and Cyclone are the fanciest non-Campy hubs I've run.

If you can send me some 32 hole Dura Ace and Superbe Pro hubs, I'd be happy to run some tests for you.

Oh and whatever the fancy Sram hubs are called. Red, is it?
