Sourdough, I have the Weber Q and use the grill mats such as the ones in the link. I cut them to cover just 1/2 of the grill area otherwise it won't heat properly. That baby gets pretty hot and I grill steaks on it all the time. The mats are great because they clean up easily. I even cooked eggs on them.
