I was also considering the American Classic track clinchers http://www.amclassic.com/track_clincher.html

They're significantly lighter than the Cane Creek wheels, but after searching it seems that they've had some issues with the hubs in the past, anyone know if there are still hub problems with these?

Yeah, the rims on the Cane Creek wheels are probably just deep v's with custom drillings for the cronos hubs.
