I put them on the smoker for 1 hour unwrapped to let the meat get some smoke. Then i foil and cook them at 275 degrees until they reach internal temp of 120. Then I take them off the smoker and put them over coals or gas grill and char the outside(reverse sear) until the internal temp reaches 140 degrees. I save the juices that were in the foil, set the loin back in the foil and pour the juices back over the loin and let it rest for 20 minutes.
