More is better. And unless you are very very good, or very very lucky, you will discover that brisket is always an adventure; ...why aspire to small adventures?
As Colt says, enough smart ass, but I always get packer cut and always save brisket for the all-out, early morning or overnight type of cooks. There's just something about the challenge. You are doing some serious cooking, not just trying to make something to eat. It's Zen ....you are the fire.
It was like this when I got here.
