In response to JT:

Same chain, same cassette, same crank. I had swapped them all out a couple weeks ago. When shifting and turning the crank by hand, it indexes into all 10 cogs without issue.

The one thing that I found odd though was when adjusting the B screw to get the 6mm gap outlined by SRAM in their installation material, I wasn't able to get it down quite that small as I backed out the B screw.

I hadn't even thought about the hanger, as everything was working fine pre-swap. I wasn't trying to solve any problems with the upgrade, was just looking for an upgrade. I will see if it's obviously out of alignment, and if it's not obvious, I'll head down to my LBS after double checking all other possibilities.
