I really need to try a brisket per Bludawg.
That being said, as other have said, foil doesn't breathe as well as paper. I get more darkening and a better bark with paper, texture overall, has been better with paper. Before that, I basically did unwrapped. I add some moisture when I use BP and have not had problems, save for the time I had not properly folded the paper, and it unfolded as I carried it into the house. I now use a pan or board.
Whip It Off, Chambers!
