i talked to our shimano guy today and he said that because of the way the new 7900 chainrings are shaped, the new chain works really well w/ them, but would probably not work as well as a 7800 chain on 7800 rings. that said, it seems that to benefit from the new chain, you need to have the new rings. who knows, it might work just great on campy rings...probably worth a try.
