How much coal do you put in the bowl? I usually fill it up so I don't have to worry about adding more but that makes me think it might be too close to the plate setter and the cause of some of my dried out issues
205 seems way too long given my last experience (I've done about a dozen) I'm thinking about 198 this go around.
I'm also considering wrapping in foil - which surprises even me. But I did it with spare ribs two weekends ago doing 2-2-1 and they turned out great
Temperature is not how you judge a brisket for doneness! It's good info to have, but not what you base decisions on.
I don't use my egg for briskets (I have a gravity feed smoker that I prefer), but I used to. There are 3 types of heating... conduction, convection and radiation. Conduction is not really at play here (minor bits where the brisket touches the grate/grill, but negligible). Convection is what you want, and what BBQ is based on, historically. With offset smokers, it's ALL you have. With an egg, you get a LOT of radiation heating if you don't use SOMETHING to block it. Water pan, place setter, whatever, but to me, that's the main difference between eggs and true smoker pits.
You don't have to wrap, but I do, and I think it gives a lot of protection against drying out. The beef tallow suggestion above is a great one! What I do is wait for the bark to set and have good color. Whenever I get there, I wrap. I use butcher paper or butcher paper AND foil (bp on the inside, foil on the outside). I pour half a beer and a good amount of beef tallow over the brisket and seal it up, then put it back on the grill.
The way I check for doneness: I monitor the temp and wait until it reaches 200. Now I'm done with the dial on the thermometer. I DO use the probe of the thermometer from here on out. You want the probe to slip into the brisket with about the same resistance that it gets when inserting it into a jar of creamy peanut butter. I ACTUALLY PRACTICE POKING A JAR OF PEANUT BUTTER TO GET THE FEEL and when the probe feels the same in the brisket, that's when it's done.
Rest in cooler at least an hour, and up to 6-8 hours, depending on your plan for the day. You can wait longer, but you probably need to hold it in an oven, not a cooler, for those situations.
