I've now built two sets of C2's, both 32 hole sets, one with Dura Ace hubs and one set with DT Swiss hubs. I LOVE them. The bigger tire feels better, especially when turning, and they have held true for me at 320 lbs. on full carbon bike. My buddy, 240 lbs., has built A23's and also a set of C2 wheels, and he's very happy with both. He built the C2's after seeing how well mine ride.
