My beloved daughter has set me up with dry rubs she buys when she's out touristing on vacation and goes into stores that sell that stuff. My wife runs a home daycare and I've been lucky enough that two of the dads have also bought me bottles of dry rubs since they're into grilling and smoking like I am. I'll use one type or mix and match when I'm not using one of my own concoctions.
Your weber sounds great!
I dry brined the chicken, but since the others were my wife's sudden surprise, we just used rub on them. She has some rubs she bought, I'll need to see what they are. So maybe I undercooked the beef, I'll have to experiment!
Experimenting is the fun part! Also, we brined a Thanksgiving turkey one year. We might have made a mistake but it turned out so salty we've never done it again.
