So I am a Trangia 27 fan of, cough 30 years, and its the dinosaur in my backpack. The issue I find is its the only way I know how to cook and I can cook anything, regular or specialist foods, the simmer ring does a good range of cheap foods. Plenty of dried foods you'd get in regular stores are basically add to boiling water and simmer for x minutes. Now you could use a pot cosy to produce the equivalent of simmering?
I have the Duossal pans, they replaced some pans which were black and pitted and not sure much longer they'd last, the Duossal ones seem likely to last much longer.
I have the kit with the kettle and I like the kettle! The issue is, and I weighed this, my total cooking kit excluding the fuel is weighing more than my 2-skin tent! I can leave the kettle and boil in the pots, that's only a little hardship, but I've tried moving down from 2 to 1 pot and it creates a need to bring something to eat out of, true a plastic bowl is likely lighter than one of the pots but the 2 nested pots is far neater. I could do without the lid, I never cook in as a frying pan but I do use it to keep stuff warm and to keep the pots off the ground and to accelerate cooking times, and the lid makes a secure package, so I don't really want to leave it behind.
I look enviously at some of these weights say of the Caldera Cone or there was a sale of the Jetboil Sol Ti but they are basically 1-pot solutions. Is there anything better out there?
PS in UK there is a Trangia clone made by Gelert, they don't last, the metal is sooo thin they are bent and need to be bent back and don't last the decades that a Trangia does.
