Thanks you all, I minion with a full water pan and 4 or five nice chunks (small fist size) pieces of hickory a couple buried in the unlit charcoal. Used this to rub using only half the salt called for and 2 Tbls. of cayenne.
Rustic Rub
8 tablespoons paprika
3 tablespoons cayenne
5 tablespoons freshly ground black pepper
6 tablespoons garlic powder
3 tablespoons onion powder
6 tablespoons salt
2 1/2 tablespoons dried oregano
2 1/2 tablespoons dried thyme
Cooked for about 6 hrs. at 250F to 260F. Let them rest for 20 min. Probably should have pulled them off 30 min. sooner. They were a bit softer than I like but my wife likes them that way so all was good. The funny thing is although they are very dark, they have no "burnt" taste to them. I don't know, maybe the paprika darkening? Anyone?
