Just as an FYI, Reynolds does make a heavy duty foil and has it in wider than standard rolls. After I tried to foil my Traeger junior with regular Reynolds foil, I switched to heavy duty and never looked back. I pretty much only use regular foil for tenting resting meat, baked potatoes, and under food on a baking sheet when using the broiler to toast and melt cheese on a sandwich. When foiling drip pans it creases easier and stays tighter to the tray (which should affect performance less).
I buy 2 big rolls of heavy duty at a time from Costco.
