Hey another thing about rubs. There are some other ways to add flavor. Kind of time consuming, but well worth the effort. Before applying the rub, cut small holes in the brisket, stuff with whole garlic cloves. Here's something that will add flavor, cut up white onions, green onions and garlic (really small/fine), add to melted "real" butter to form a paste-like stuffing and fill in the holes, cut a small piece of fat and close hole to keep stuffing in. Rub and smoke. If you have enough patience to make a hole length-wise and stuff it that way, every piece will have that unique taste. "Real" butter is a great flavor.
