I have been reading, but haven't seen anything conclusive yet. I'm happy with alcohol, but there may be times I need to burn something else. Kerosene appears to have much to recommend it, but I wouldn't mind being able to use White Gas, LPG, etc, since I'm thinking of investing in something. I note the Trangia X2 burner is deliberately de-tuned to avoid overheating the aluminum windscreen and pots - I'd like to hear about that aspect of any recommendation. I can buy an X2, I can buy something else and an adapter. I won't use it often, I'll use alcohol mostly. What would be a good investment? I have a 25 all HA and a 27 Titanium with UL windscreens. All the discussion will be of interest, and thanks for actionable opinions, too.
