Side note, MSR dragonflys are the shit. I love everything about them, the literal drink bottle of petrol you have to carry around, the crazy aluminium foil windshield, the pumping, the way they spray fuel everywhere as you light them, then the tower of flame that almost burns down the building as it primes. Cheap to run, indestructible, perfection.
I liked Quora as recently as a few years ago, it had some nice explanations that you couldn’t get anywhere else. Obviously you have to take everything with a grain of salt, but you have to do that anywhere on the internet.
