I agree that you can get too much smoke. When I do a brisket, I season it liberally with kosher salt, course ground black pepper and garlic powder. Put in on the smoker at 225F for about four hours and then wrap it in foil and finish cooking it in the oven for about another four to five hours. There is no need to continue it on the smoker wrapped in foil, as the smoke can't get through the foil. By putting the brisket in the oven, you have consistent, low heat that is controlled and you don't have to maintain the fire like you do on the pit/smoker. It is ridiculously tender and delicious!
