For commercial rub you can't go wrong with Butchers BBQ. The premium rub on pork. The honey rub on ribs and chicken. And the steak and brisket rub on beef and cheese. I tried his prime injection on a chuckie the other day and it is amazing. He also has the best sauce I have ever tried.
But you can't go wrong with plowboys yardbird or drapers ap rub.
