I am looking for advise on rub or not to rub. If so what would you use? Starting with around a 4 pounder. Going to to roll it with simple things since the kids are really picky. Probably just bacon, mushrooms, and cheese. I have not done any loins before so how long for this size? My smoker holds temps nice around 230. I was planning on laying some bacon strips on top also. Using apple wood for smoke. Q-view to follow later today.
