Hi Al, Try John Henry's pecan rub, it is fantastic. Lately I have been doing a base rub then a lite sprinkle of McCormicks Grill Mates Montreal Steak Seasoning. I just adds a bit of a kick to the taste. Sam's Club had that in a 28oz bottle. Glad you liked the chuck roast I pulled mine and made really great sandwiches. Also you should try a Boston Butt pork, as they really are good. But, in reality anything you smoke in these smokers are great. I smoked a 7# one in my #1 and it pulled very easy and had an awesome taste.
