It actually seems to be coming from the pulleys, most likely the G-pulley. Just guessing, but it seems the lateral movement in the pulley is causing the sound. Purely a guess.
I'm not able to give my full attention to it tonight, unfortunately. I will have to diagnose tomorrow.
Sorry to lead everyone on a wild goose chase. Like I said in the original post, I was convinced the noise was coming from the chain/front. I'm honestly still not convinced the rear noise is the same as the noise I was hearing. Sometimes it helps to take a break - hopefully this is one of those cases.
If nothing else, I learned about Chain-L.
