Donna,
That's what works for me. I like bark and wrapping softens the bark too much for my liking. I also find it difficult to tell if its done when it's all wrapped up.I prefer to look at it, probe it and jiggle it a little to determine its doneness. This particular one was done just a few degrees lower than I had expected. Since it was a USDA Prime cut, I just expected it to be done at a lower temp. I also let it sit out unwrapped on the counter in an aluminum foil pan for a good hour, until it temp'd at around 150 before I sealed the pan with foil and rested it in a warm (heated to about 170, then turned off) oven for another hour until the beer arrived.
When serving it, I sliced it in half first (about where the point overlaps the flat), and then took the slices towards each end. I think the slices are juicier in the middle and why not serve those first? Sliced and chopped up the rest of the flat for brisket tacos the next day. Damn good eatin'.
