Millions of cooks were doing it before I started...but That is the way I cook them on the Memphis Pro, it really is an easy process and they are rarely over cooked.
I really dont recall what temperature Larry cooked his at on the PG1000, it certainly grilled in zone 1. He had and elaborate process with the Lawerys seasoning, the Soy Vay Teriyaki. He would start in zone 2 or 3, then move to zone one, then finish with cheese in zone 4. He like to flip them about every minute, never quite got that.
