Actually, I think this other thread below has the most complete list of ingredients I tested. The thread you are currently reading was just the first one I posted here on this subject. I made two other posts after testing some other things, with the one below being the most recent one.
Also, you mentioned you were starting to make rubs. You may or may not find this spreadsheet helpful. In case you do find it helpful here's a thread with a "spice matrix" I built while studying and researching ingredients and flavor matches.
