Rubs that I have tried and enjoyed
Oakridge
Black Ops - on beef layered with some salt and pepper.
Simply Marvelous
Pecan Rub - goes well on everything
Sweet Seduction - Layered with Cherry Rub on ribs is the bee's knees
Cherry Rub - Goes well on pork
Peppered Cow - Anything beef can use this.
Plowboys
Yardbird - Goes well on pork and chick. Watch out when putting on the smaller cuts of meat (chicken or ribs), it is salty. A pork butt can't get enough of this on it.
3eyz
Pork - This rub goes great on anything pork or chicken.
