I usually just marinade with Moore's for a day or an afternoon. The rub I used last time which I thought was very good was a Lemon/Garlic combo made by Tone's, I believe. Used some Kosher salt and then a light dusting of cajun seasoning. Oh yes, my secretary had given me a cajun injector with a bottle of garlic butter, I think. I shot it up with a good bit of that and really thought it came out great. Pulled it around 140 and let it rest and climbed to 145-150.
