Hey, I'm still surprised to find polite online conversation!

At any rate the heaviest foil is still usefull, it just isn't as good as it use to be. Doubled up it still works pretty well. When I can't smoke ribs, I'll wrap a rack in plastic wrap, then heavy foil and roast at 225 for 2.5 hours. Generally the foil doesn't burn thru at that time/temp combo.
