I put the point on top. I like butcher paper, retains the better bark. When the point hits like 190-195, cube it up and toss it in a pan with some sauce, honey, and more rub, then return it to the grill. When the flat temp stops increasing (somewhere around 200-205), take it off and let it rest in a well insulated place. Cook the burnt ends until they brown to your liking while the flat rests. You won't really need to rest them.
@n_huffhines : I think it's just the fat content of the point that often makes it difficult to neatly slice. Just another reason to go burnt ends.
