Reverse Sear is the way to go!
Perfect medium rare edge to edge.
Room temp roast. Cover with olive oil then course salt and any other rub you like.
Oven 200 degrees roughly 5+... hours until internal 125.
Pull out let rest an hour, it will probably go up to 135 internal while resting.
Put back in at 500 degrees 10 to 15 minutes to make a nice bark.
