I prefer to cut the rib section into rib chops and direct grill them to medium rare. Cooking it whole may not be a bad idea, just matter of preference.

It's the neck/beginning of the ribs.There is no part of the tenderloin on that piece.That triangle shape bone on the left in pic #2 is the shoulder blade.
