Oops - got in a hurry and didn't realize the post you cited was for the 3-2-1 method. Personally, I find that of no benefit, and prefer fitting the ribs into my Lazy Q lifestyle by avoiding all that foiling, removing, juicing, blah blah blah... Just remove the silver skin (the membrane on the bone side), coat them with mustard or oil, rub, and put in the smoker! 2.5-3 oz. of wood and a juice pan on the floor of the smoker (next to the smoke box). Close the door, and don't open it for at least 5 hours. Check for doneness with a toothpick. If it goes in easy, and you can pull the meat from the bone, without it breaking, they're done! If not, go another 30 minutes and check again.
Keep it simple - 5 hours no-peeky! Perfect ribs, great bark, every time!
