Jeff, these guys are straight up. You might get the cook time down to perhaps 6 to 7 hours hot-n-fast, but faster will be at a huge sacrifice, and frankly you wont sell much because word-of-mouth will tell folks that your product isn't good. Your briskets and pork butts are going to take 8-11 hours; they just are. You can hold them and not have to re-heat them. I've held both for 12 hours and still had them burn my fingers when pulling. You can cram ribs in 4 hours without a problem. Chicken can be 30 minutes, or an hour, depending on how you do it, temps, etc.
Dont underestimate the insurance.
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.
