Bought a MES30 (1st gen) last week, also bought a AMNPS.
Just smoked the flat
Just did a basic salt/pepper rub and I was very happy with the results.
Set the smoker at 225 and it stayed between 225-235 the whole time.
I probably opened the door too many times trying to keep the AMNPS lit and chekcing on it (5 or 6 times).
Didn't wrap it at 160' just waited and let it go to 200', pulled it, wrapped it in tin foil/towel, let it sit for an hour in a cooler, and sliced.
Once everything was done I was very happy with the texture and flavor but it was dry.
