Well, I am a salt and pepper smoker for most things, but here are two rubs that I use:
Pork Ribs = 1TBS cumin, 1 TBS paprika, 1 TBS garlic powder, 1 TBS onion powder, 1 TBS chili powder, 1 TBS brown sugar, 2 TBS salt, 1 TSP cayenne pepper and 1 TSP pepper - coat the ribs, and let them sit overnight wrapped in plastic in the frig.
Chicken Wings = 1 TBS salt, 2 TSP pepper, 1 TSP garlic powder, 1/2 TSP tumeric plus make a glaze of 1/2 stick of butter, 1/4 cup of honey and 1/4 cup of Cholula (less for less heat) Smoke the wings for about 2 hrs then high heat/regular grill for 15-20 minutes to crisp them while applying the glaze
