93slayer, another technique that helps with heat recovery when you put large amounts of cold meat into your smoker is to put a foil wrapped brick or two in the bottom of your smoker. Put the brick in so it heats up during the preheat period. This gives you a hot thermal mass that will release the heat it has stored to the cold meat. A smoking brick also helps with heat recovery when you do things like open the smoker door to check things or to refill the puck bowl.
I have even been known to preheat a couple of bricks in the oven (to 400 degrees) on a cold, damp, windy day, to help along a still very cold (OK, there was still some ice in the cavity when I took it out of the fridge) turkey.
