I've only had my wsm a couple months and so far I've made about 20 racks of ribs all of which have been absolutely stunning have even made them for family and friends and heard they were the best they had we'll decided to finally do pork butts since I can't afford a decent brisket anyways I bought a pair of Bone in butts 15.50 pounds total I figure 225 or 250 but how long and inject or don't inject when to foil etc all advice is greatly appreciated
