I use the pans all the time, but not until it is time to wrap the meats. As stated earlier, the pans will limit the amount of smoke your getting to the meat. They are relatively inexpensive, half pans are about .25 each and the full pans are about .50 each at Sams'. On smokes when I wrap, I place the meat in the pans and cover with wide alum foil, on smokes where I don't wrap, I still place the meat in the pans around the same time as when I would normally wrap, I just leave the cover off. This allows you to catch all the goodness, but still take on smoke and build a killer bark. I also use the wire mesh cooling racks in the pans to keep the meat up and out of the juices from time to time, especially with pork butts. I'm not so worried about briskets sitting in it's own juices asI cook fat side down so the fat layer is in the juices not the meat.
