I had a pair of CC Aeroheat's or whatever they were called some years ago. 24/28 spokes, and nips at the hubs too I think. But they felt too soft laterally. I'd get lots of brake rubbing on hard turns.
Maybe the Volos XL are better now in that regard, I don't know. I'm tellin' ya though - just buy a set of Campy Vento's or Scirocco's and you'll probably never want a lesser wheelset. They can be had with a Shimano-type freewheel, so that's not a problem. Good prices can be had if you search around some.
