Good call on the heated rest...I'll be patient! But what did you think about the cooking performance of yours?
Mine cooks very evenly and forgivingly with a strong draft, and temperatures have been easy to control once I got the hang of burning full size splits on a medium to large coal bed, controlling the burn rate by varying whether I press the splits into the coals or allow them more air contact by placing them loosely (see Jirby's fire management video). I have run it for cooks as low as 200 and as high as 325 - 350, and it produces good results for me throughout the range.
Yesterday, I served a prime brisket for dinner to my family and my sister in law's family that I had rested in a sous vide for 18 hours at 143 (similar to Chud's video) prior to serving...sorry no photos as we were all hungry and ready to eat. The in-laws all came back for seconds, and my wife said it was as good as Wright's in Fayetteville, so I was pleased with the positive reviews.
