I've done some searches but couldnt find what i was looking for. I'd like to foil my butt as I've found it tends to finish quicker and my experience has been a butt that is more tender and juicy. I'm sure that may not be the rule, but having done it once or twice, it worked well. However, i can't remember at what temp to foil for the best results. I'm at 159 now and 7 hours on a 7.5lb butt. I was thinking 170 is the target temp for foiling, pls advise. thank you
