made this last weekend and it turned out fantastic! I followed this recipe: http://www.thewolfepit.com/2009/10/pepper-stout-beef.html
Coated the chuck with SPG and then a layer of zesty rub the night before and put it in the fridge overnight. Then smoked on the weber kettle at 225 until IT of 165. pulled it and placed it on top of the veggies and placed in the oven with the rest of the ingredients covered at 350. It was done when it was easy to pull apart. Tasted great both in a sandwich with some melted cheese and in quesadillas!
