I have a recipe at home that I use that is very good. I'll post it when I get home.
Do you have a smoker or are you using a gas grill? If you are using a gas grill they sell small cast iron boxes that you can put wood chips in to smoke it...they only run about $15 so its worth the investment.
also check out this guys books...any of them are good and contain some great BBQ recipes.
