Both cuts of meat need to rest for at least an hour anyway, to ensure the juice stays in the meat.
12 hours? Based on what cooking temperature? What size of meat?
It all varies depending on both of those, and frankly how well your individual smoker circulates the heat & smoke. Every one is different.
I know I can cook about 200#'s of meat on my Lang, at about 265 degrees, and depending on how large the cuts are, they're usually DONE from 9 to 10.5 hours. Again, your smoker will be different, I assure you.
