Trim very close to remove any hard fat or silver skin on the outside edges that won't render.
Season with whatever you feel is your favorite about an hour before going on. Keep cold (<40) before grilling. Definately do an idirect grill up to an internal of about 125-130, Then direct grill about 2 minues per side to get the char. Let it fully rest afterwards.
Very easy to overcook it so be careful to pull it as soon as it reaches temp. I might even be tempted to forget the char and pull it when 130 is reached, but then I like mine with decent pink in the inside. If you or your family likes it more done then maybe take it up to 140 but be sure to let it fully rest afterwards. It will continue-cook beyond your pull temp so don't be fooled.
