I can't report on any of the rub flavors, but for a competition last season we used Kosmo's injections. The chicken soak is a very good product and instead of brining, I wound up injecting the thighs about 90 minutes before putting them on the smoker. It's also really good for pork steaks or pork chops. And, it mixes in a shaker with room temperature water, so it's ready to go in 5 minutes. The shoulders were injected with Kosmo's Original Pork mixed with apple/white grape juice. And for the brisket we used Kosmo's Reserve Blend. By far the Chicken Soak is my favorite, next was the brisket injection, very beefy and held moisture well, and although the pork injection was good, I've had better success with a home made one for shoulders.
