I received my 5 x 8 A-MAZE-IN-PELLET-SMOKER yesterday. Will try it Sunday on some Baby Back Ribs using Jack Daniels Pellets. After reading thru several posts about the light smoke, hardly visible smoke, can't see the smoke, and etc. I am now worrying about it producing enough smoke. I bought a small wire rack about the same size as the smoker at Ace Hardware tonight to raise if up off the bottom grease tray a few inches for better air circulation. Is it going to produce enough smoke or should I fill Smoker tray and light both ends or ????? This is my first time trying this Smoker so all help is greatly appreciated. In reading descriptions tonigh, I keep wondering if I should order a 12" Tube? A description of tube vs tray is 6" tube .... 1/2# pellets .... lasts 2 hrs 12" tube ... 3/4" pellets .... lasts 4 hrs 18" tube ,,, 1# pellets ...... last 6 hrs 5 x 8 tray .... 1# pellets .... lasts 10-11 hrs Summary, if 1# in the tray last 10-11 hrs and 3/4# in a 12" tube only lasts 4 hrs, is the tray too light on smoke, or the tube too heavy on smoke or etc. as both burn almost the same quanity of pellets, yet the tray lasts 2 1/2+ times as long as the tube. Or should I light both ends of the tray? On the tube, if I were to get one, should I get the ends to it also or does it come with the ends? HELP .... Please !!!!!!
