I have a new WSM 18.5. Cooked on it about 4 times. Well...the other day I was holding at temp cooking a butt and notice that the temp was falling and rising. I then hung the probe from my polder thermometer in the top vent and it was holding right at 245/244. But the lid them was going up and down! Which one do I trust?
