After reading Franklin's book and some beard scratching, I'm in the same place. When doing a minion, I toss a good-sized chunk of wood into the chimney when starting 20-ish coals. I put all the other wood on top of the unlit coals and try to make sure that each piece of wood gets some lit coals to get it going. It takes about an hour for the temp to settle and the smoke to get to a nice light stream. I find that the bark is less bitter when I let the fire settle in. (I also find that spritzing with some apple cider vinegar about an hour before the brisket is done also helps the bark.)
On the other end, a long rest is important to a good result. Several months ago, guests were delayed and I ended up resting a brisket for almost 5 hours, wrapped in foil and in a cooler with towels. I couldn't believe how moist and tender it was (temp was about 145) compared to a 2-hour rest. I plan on a 4-hour rest and the results have been very good.
If you like smoky brisket, Black's Lockhart has the deepest, sweet, smoky bark I've had in these parts.
