Several things I learned with this cook, a large baking sheet on the main grate deflects the heat and tricks the thermistor, grate temp and door thermometer were reading the same which was about 30 degrees lower than set point,i had the brisket on the top rack to see if it changed the smoke profile,not sure my old taste buds could tell a difference. I think I have figured out what is missing from the smoke in pellet cookers and its the harsh bite from hickory that mellows out oy after a long cook, might be knocking some bad carcinogens out of the mix that might not be a bad thing for me, cancer is bad in my family,sister was diagnosed with lung cancer last week, she is 3.5 years younger than me
