Some great suggestions already, allow me to add Kosmos Dirty Bird Hot.
Tried the Fire Dancer rubs after listening to Malcolm Reed's podcast where they did comp chicken. I used it on wings with no type of sauce and I actually liked it a lot. Will be using it more in the future once the new smoker is finished to see how much I really like it.
It is a great rub and he is a super nice guy, glad some people are buying his stuff.
How's it compare to Yardbird?
Chupacabra rub, both the regular and the Cluckalicious.
