6.5 lb just flatthat is a broad question... not sure about a MES...I use a pellet. my preferred cook temp profile on the the pellet grill is 180 for 3 hours then 275 till probe tender. I start checking the tenderness over 190 IT, its usually done more like 195-200. I stopped wrapping, but those who wrap with foil or butcher paper usually wrap at 160.
I am sure a MES user will have more specific tips for that cooker.
Full Packer or flat only? size?
Ok and what kind of smoker temp do you try to keep?I always do fat down on a flat. trim fat to about 1/4 inch or so thick. I would probably wrap a flat at 160.
Sorry missed thatmy smoker temp profile for a brisket is above in my first reply
