I bought a piece of meat that said "Tri-tip roast" on the label. Since it said roast I cooked it like a brisket. May not have been the Corte t way to do it, but It was great and there werent any leftovers. I will probably not add bbq sauce in the foil if I do it again. I might go see if they have any more and do a reverse sear.
Ps. Montreal Steak is my go-to for steak, until I figure out something I like better, or make my own version of it.
