That brisket looks real nice. Gotta say I think your cook would go a bit faster and your fuel consumption would be reduced if you left the cooker closed. I wouldn't have even peeked at that thing till the internal temp hit 190.
Progress pics are nice and all, but not at the expense of a nice hassle free cook with great results.
