Oh yeah, I use the simmer ring on the Trangia big time. It works so well that I really fell in love with that stove. I took the Caldera Cone tri-ti wood burning insert and inverted it to use as a general windscreen with the SP 1400 cook set. Super light and fits tight. The ventilation slots at both top and bottom really makes this an efficient setup. With the ti stakes the pot is 1.5” above the burner, the perfect efficient distance. With the Kovea remote canister stove no stakes are needed, the stove supports do that. The pot fits tight enough to kind of pick up the cone. Not the way Trail Designs intended but works amazingly well.

I’ll simmer for 40 minutes or more at times. The stove easily handles that. I’ve found the stove and simmer ring need to come up to operating heat before closing down the ring to the most constricted extent. Then it’s hard to put out. Even the little hole at the pivot wants to keep a flame. Lol
