Ed, I agree with Kari and Dave completely! Spritzing, opening, yada, yada, yada, is SO counter-productive with these smokers! I say "If it ain't broke, don't fix it!" I have to say that no-peek ribs, with a water pan for the right amount of time, are fantastic! One thing to keep in mind, too, is that sometimes it's the meat! I have tried a different source of ribs before, and they were definitely not up to standards. The source of the meat does matter!
Bottom line? ...Stick with the formula that just "works!"
