Plan on a longer smoke. The longer you take it over 165 internal without foiling, the more bark you will get. Make sure you have plenty of sugar in your rub since that is what caramalizes with the other spices to help form the bark. A good sweet spritz like apple juice helps as well. Depending on what flavor you are looking for a 50 - 50 mix of Yoshida's and beer is a great mop too!
