Just some thoughts about this statement :
"To summarize the fuel stove debate ,is , as the salesman i spoke to suggested in Hobart, Trangia best for long trips and Jetboil type stoves best for 1to2 day trips ?"The only characteristics that the two stove mentioned have in common is that they are a complete system : burner/pot/windscreen, are simple/ foolproof and work in windy conditions.
The Trangia is (INMH) ideal for people that want to do extensive cooking and don't like gas.
The JetBoil (JPS ) is for folk that are after a compact easy solution to mostly boil water .
PerformanceVery roughly you need twice as much alcohol (in weight) than gas to boil the same amount of fuel.
On my scale the JPS with a 100g cartridge is
640g. That boils (conservatively) 10 L of water
The lightest Trangia* is the 27-1UL at 720 g, add 200g of metho and a container and your starting weight is
950g .
So even if you have a full cartridge and are out for a day only the Jetboil is lighter. However contrary to the advice from your salesman, having to carry twice as much fuel (in practice in cold weather is more than that...) the Trangia will always be heavier.
Having said that, those two are NOT lightweight solutions particularly for the boil water only brigade.
For example my Caldera Cone system has a total weight of
400g with 200g of metho. (550ml pot)
I can boil 500 ml of water with about 7ml of Ethanol, so about 14L with the 200ml.
If I go out for an overnighter my full kit is under 250g.
With gas, I have the very common Kovea Ti stove (sold under other brands) , that system with a 900ml pot and my around the pot windscreen (made from soft drink cans) can boil i L about as efficiently as the Jetboil even in windy conditions and is about 1/3 lighter.
Of course I don't fry, nor bake , nor attempt Cordon Blue cooking because I go out to enjoy nature not to practice my culinary skills.
* Yes I do know about the Mini Trangia, not particularly light nor efficient but "safe" if you are not prepared to research# into this.

BTW for the ones that wonder how people can use 60L backpacks for 4 to 7 days, make a mental comparison in volume between the CC or the 1 pot system compared to the Trangia. (the Jetboil is almost identical in size to the 1 L Nalgene bottle)
The shot of my gas combo is of an older prototype. It works well but only with the gas on low. In mild temperatures , the lower the setting the more efficient it becomes.
A newer version has holes punched around the bottom. Of course it is fragile and you need to make one every two or three trips but it costs nothing and is very light.
