I don't rub ahead nor do I remove the butts from the fridge early. I remove the butts from the fridge, salt them, then go out to dump the unlit into the cooker and set up some in the chimney, lighting it for a Minion start. Then I go in, make a rub (saltless, since I've already salted), apply the rub (it sticks well since the salt has drawn moisture to the surface), then cart out the butts.
Wood gets scattered on, lit gets scattered on, the cooker gets assembled and the butts go right in.
