I'll chime in... As a former AT thru-hiker, my trangia is very well used. I never have understood the argument that its too slow. You are leaving civilazation to slow down. Whats the big deal about eating dinner five minutes later, where do you have to go with that five minutes???
Simmering... The heat is a low simmer anyway. I've always just flipped my pancakes quickly to avoid burning. Never have figured out the simmer ring and never use it (asside from extinguishing the flame).
