Now there is some good info. I was indeed using a brand new KMC X10SL chain. I would use the Sram chain, but I'm running Praxis chainrings and they recommend against using a Sram chain. So my casette wants a Sram chain and my chainrings want a KMC chain. Oi!
Given that the 2011 RD runs fine with the KMC chain, what would cause this on the new RD? Is it the new pulleys?
2012 Sram Red Rear Derailleur Issue

I recently installed 2012 Red on my bike. Using a slightly used KMC X10SL chain, the rear indexes correctly. I don't think its the chain.

i wonder what is the reason for parxis recomending against sram chains. i has a similar problem with my 2010 red rd with a yaban chain, but swapped to a dura ace 7900 and things became butter smooth.
my red set up was awful with a YBN chain ...its 2011 but with KMC its spot on
