Familiarity: I've put it through the wringer
This rear derailuer provides great performance, I am using the WiFli version and the setup is simple. The shifts have been reliable with no mis-shifts. I am using a Shimano 9000 chain and the Sram system does not care one bit. Also the derailuer does a great job of taking up slack variation my Q-rings produce with no problems.
