I run 12 speed chorus, set it up myself so it did take a bit of tweaking, more than 10 speed took me, but it works well.
I didn't fork out the extra cash on the 12 speed cables as my cockpit isn't integrated so I didn't really see the benefit of the extra bendy cables.
I also didn't buy a campag 12 speed chain and went for a KMC X12.
I would say my set up is loud compared to my 10 speed centaur winter drive train which is also uses a KMC chain.
