Brickguy, I've begun lighting my
AMNPS with gelled alcohol because using a propane torch became a real pain. I usually fill 2-4 rows of the
AMNPS with wood pellets depending on how long the smoke will be. I spread the gel on top of the pellets about an inch back from the hole, I spread it on the hole and then underneath the tray like I did on top. I set the now-burning
AMNPS on the ground for about 20 minutes to make sure it's fully lit and going strong. By that time my smoker is usually at the setpoint or close to it. When I pick up the
AMNPS I blow on the burning end to get a good, red cherry. If a flame reignites I blow it out just before placing the tray in my MES 30 on the two rails to the left of the wood chip holder. I insert the AMNPS burning side towards the rear wall because it seems like it burns better in my smoker like that.
The amount of smoke time you get with the AMNPS is dependent on different factors: the temp you're cooking a and the type of wood pellets being used being the primary ones, in my opinion. I found that oak pellets burn faster than mesquite and Todd's Pitmaster's Choice blend.
The last time I smoked (which was a brisket), at about the 10-hour point I noticed that smoke was no longer rising from the top vent. When I looked inside the smoker I saw all the pellets had turned to ash. I had foiled the brisket and it had gotten all the smoke it needed so at that point I didn't worry about refilling and relighting the AMNPS for the final hour of unfoiled cooking.
As for tube or tray I guess that's personal preference. I've only had the 5x8 tray.
