Don't know if this helps or hinders by 12/27, but I always cook boneless PR (on a Roti). Shape it into as compact a cylinder as possible, tie with butchers twine to hold that shape, dry brine with Kosher Salt and Baking Soda overnight. Two hours before cooking, rinse in water, pat dry, apply EVOO and your favorite beef rub. Cook temps 325-350. Two baskets one on each side of a drip pan. HFG's coal count should work ok, monitor the kettle temp at the level of the Roti. NOW, if you want Med Rare, then check w/ a ThermaPen at 1 hour and every 7-8 minutes after that. My experience is that a PR can go from 130 (perfect for MedRare) to Med Well in a flash. Pull it at 130, let it rest and carve the best PR money can by. I always use Hickory Wood for smoke, it's PR it can handle it ... SJ
