Here is a marinade I came up with a couple months back, my wife says is the best I've done. If you don't have some of the chili powders just substitute your own. Good smoking to you.
Reserve your mainade and add olive oil for your mop. I marinaded this loin for 36 hours. I also cut it in half because of its size. Cut this recipe for the size of your loin. I also turned it in marinade when I had the chance. I smoked it with apple and hickory and kept the temp between 235 and 250 degrees. This was excellent.
