Options are endless relative to brines, rubs, and choice of wood for smoke. Main thing with any poultry, especially large turkey breast, or whole, is to make sure that your temp is hot enough to get the thickest meat sections up to 140 degrees within a minimum 4 hour window. Any slower rise in temperature gives exposure to potential bacterial risk. 200 to 250 degree smoke temps are fine for pork, beef, etc., but use at least 325+ for poultry. Wait until after the first hour of cooking at least to probe, to prevent exterior raw factors, from being inserted to interior portions. Needs to get to 165 degrees, but I usually pull off the smoker at about 160, tent, and let rest, and usually will residually come up to the 165 mark. Happy Thanksgiving.
