OK guys got a few questions for yall. I plan to pick up a AMNS for my new 40"MES the wife got me for Christmas. I've done a few cooks on the MES so far.I get great smoke at higher temps but not so good to none with lower temp. Nothing new right. After a little reading looks the AMNS is the answer. First question.I need to know your opinion on what size to get. I'm thinking the 6x8 would work the best for me. Is this correct? Second question. Does the AMNS need air to operate properly? I may be new to this electric smoker but I'm no novice when it comes to smoking. In years past i always used wood/charcoal cookers. They all have and need air dampers to work right. This MES has no air damper on the bottom. Only the vent in the top. And it seams fairly air tight.Will the AMNS work right with out good air flow? Should i remove the chip dispenser...that might help?? Thanks for any help.
