I have made a Campy short cage shift a 12-30 with a bit of head scratching.

I tried a Miche 13-29 and almost immediately went to Campy. It just shifted like crap. I might have gotten a bad one, but mine was loud and sloppy. Sounded like gravel in the washing machine.

I've been happy with Shimano, Campy, and KMC chains. Campy is a teeny bit better, most wouldn't notice but I'm kind of a perfectionist (or a princess).
