Last night, I tried a slightly different recipe, smoking it for 6 hours, then finishing the rest of the way at around 220 degrees, low and slow. Came out perfect. I'm really getting the hang of brisket, I believe, just need to keep working on ribs.
I put it on at 2am, just on the Traeger Lil Tex Elite grill, and then at 4:30am, put it in a foil pan for the rest of the time, till it got to 210. I kept the temp around 220-230 the whole time, so it really was low and slow.
