I have 2 Mavericks that I haven't used in many years. I've never needed the air-flow gadgets, etc.
For years and years its just me, the wood, the charcoal, the old Lang (it has one old external mounted thermometer that is 40 degrees off), and the meat. That's it. I go on time. I know if she's running on the hot side, my times will be reduced, and correspondingly if cooler the times will increase.
I just have. It's much more relaxing, and frankly the product has stayed the same or slightly better...
Hance - Lake Dogs Cooking Team - MiM/MBN/GBA CBJ and comp cook
Lake Sinclair, GA (strategically about an hour from darn near anywhere)
Started competing in chili cookoffs back in the 1990's and have competed in more than I care to count. I became a CBJ in MiM in 2005, then MBN and in GBA in 2010. I've probably judged 130+- BBQ comps (sanctioned and unsanctioned) over this time. That said, I really enjoy competing more than I enjoy judging, and hope to get back to doing 4 or 5 a year in the near future.
