I usually mix up my own. Most commercial rubs have lots of salt and I need to watch my sodium intake. Ive been loving Meathead's Memphis Dust since discovering it last Summer. I tweak it a bit based on where I'm using it, but found it to be great on chicken, ribs and pork chops. For butt, I use Chris Lilley's injection/rub recipe, but cut the salt in half. I don't do brisket enough too have a regular, but I bought a big jar of meadow Creek brisket rub last Summer that's pretty good, but still salty for my taste. I just go really light with it or dilute with some other ingredients, like more paprika and garlic powder.
