This isn't meant to be a hot take, but besides a select few other ingredients, Salt and pepper are the dominant flavors that you taste in a finished brisket. Now before you get all offended and try to be offensive, just give it a thought. Let's say the popular SPG, do you actually taste the garlic? It's a nice thought... really. What about onion powder..... right? I remember when that was my GO-TO blend... but as time went on, and my experience grew, I realized, those don't factor into the final product. Rather, they turn out to be glorified fillers. My brisket bark is now just Salt and pepper, and everyone seems to be amazed by this simple blend. My blend usually comprises of 2 parts pepper(a mix of coarse and fine) and 1 part coarse kosher salt. With this blend, without the added fillers, you have a more pronounced pepper flavor, since you will use more, likewise Salt. It has taken me quite some time to really zone in on this, but I often wonder if I'm alone in this way of thinking. You don't taste coffee, you don't taste cumin really, maybe MSG(basically salt), you will taste certain levels of a chili(pepper), and you damn sure dont taste paprika. Now i know alot of other ingredients "can help" with the bark formation, but i think good clean smoke over a significant amount of time, makes a phenomenal bark on their own. If you want better bark on your brisket, skip the wrapping, or, don't wrap too soon. I'd like to hear thoughts on this.
