I been mainly playing with Heineken cans, even though I despise the taste of it (I am a home brewer), I tried using Diet Coke cans, my wife drinks those, and I have tried using the Heiny can as the fuel pot and using the diet coke can as a burner (without crimps).

The Diet can + Heiny can resulted in what looks good, but didn't prime as well my other attempts. I imagine the crimps act as heat radiators and get the temp of the alcohol to a boil quicker.

I am wondering if I can cut tabs into the burner can instead and bend every other tab inward at a 45' angle to result in the same concept as a crimp.... Wish I still had that old crimp roller that my dad had when he was doing sheet metal work.
