I brine all pork, chicken and turkey. Butts and whole turkeys overnight in a cooler with ice water and chicken pieces for a few hours. If you have any doubts, try grilling 8 pork chops. Brine 4 of them then grill all 8 together with only you knowing which is which. Let people blind taste them and see what the results are. You MUST rinse them very well before seasoning. Just my .02...
I also inject my butts with Cherry Coke. Sounds strange but works well.
