text: Bradleys are pretty good, (I have 2) but they do have a temp swing that can be 30 degrees or more, so cook times are hard to predict. A PID controller reduce that. Key to performance is making sure there is enough air flow between the racks. A couple of bi briskets can "clog" it up and cook much faster than the stuff above. As for winter time use, they have more insulation than a Trager and you can always wrap them.
