Nice write up Mr. Peas
you're right, and it's been said before that it's a tool... The challenge here is knowing when someone should use a tool or if they really need a tool at all... Too often the rookie cook tries to incorporate everything they read at once.. and just a few cooks into their new hobby you've got a guy with a lot of ambition, a new pit, cooking a challenging meat with a counter full of reynolds wrap, injectors, spray guns and five conflicting rubs recommended on a forum. It can go downhill fast.
FYI - The reflectivity of bright aluminum foil is 88% while dull embossed foil is about 80%.
