Very funny. Pepper + Salt (Kosher) is all that is needed with beef, especially brisket. Some people use as high as 9:1. I use closer to 4:1 due to my audience. Adjust depending on your family's pepper tolerance.
Seriously, beef needs nothing more than pepper, salt, and smoke to be the most incredible thing you've ever eaten. Everything else interferes or mutes the flavor. As a reformed "over spicer*" of briskets I understand the urge to get creative, but don't. Just don't. No crimes against beef need to be committed this weekend. Please. I beg you.
*Believe it or not, in my early days of making brisket I thought the greatest thing ever was to coat the entire brisket with that pre-chopped garlic crap that comes in a big jar. You know what garlic cooked over smoke for 15 hours does? It burns. You know what burned garlic tastes like? Bitter charcoal. Don't be me.
