It is not needed but if you really want to do both, Brine with just basic Salt and if you wish, Sugar, I don't use it, in the brine. Then Inject with some more flavorful injection. Maybe Creole Butter...
http://www.smokingmeatforums.com/t/123175/creole-butter-recipe Below is the brine I use. Use as is or drop the herbs and spices. The Rub will work with either the Brine or the Creole Butter Injection. BTW... Drop the Sugar in the Rub if you plan to smoke over 300°F, it will burn...JJ

1-11/2Gal Cold Water to cover Chix

Mix well and Soak the Bird over night or up to 24 Hours.
Remove the Chix, rinse if desired and pat dry with paper towels.
Place in an open container in the refrigerator overnight or up to 24 hours for the Skin to dry.
