Has anyone tried mating a Campagnolo Record 10 speed ergo shifters with Shimano Dura Ace 10sp cassette, deraillers? Does it actually work? Any shifting problems? I have a Shimano wheelset and a Record 10sp shifters. Am I better off buying a cassette conversion from American Classic?

Check out Hubbub's website (www.hubbub.com). They've built some bicycles with Campagnolo shifters and Shimano drivetrain.
