So I need two stoves to heat up hot water ????? Why carry two stoves when one will do?
I am all for saving weight, but I also believe in the KISS principle, too!
I found that my trusty propane did not work very well at all a few weeks ago in single digit tempts. Switched to the white gas unit I thoughtfully packed and I was rocking again. (It was Coleman two-burner. Can use propane with the converter or the original white gas.)
Likewise, when I winter backpack, I'd rather not futz around with sleeping with my canister, lighting another stove to get one stove working (?), etc. etc. etc.
Carry my Simmerlite and call it good.
Of course, 'winter' backpacking is such a nebulous term. Winter at Springer Mtn in February is not the same as Mitchell Lake in Colorado at 11k ft. (I've been to both places in February..they are a tad different!
)
Then again, backpacking in Hawaii in Feb sounds rather nice...if a bit different as well.
All depends on what you do, how much snow (if any) you want to melt and how many coconuts are available for drinking out of (see above about backpacking in HI in Feb... has a low 70F currently!!!)
Etc. Etc. Etc. Thank (Insert Diety of your choice here) there are so many choices to backpack with.
Don't think anyone addressed the OP, but the 'green ones' are straight up propane vs the mixed propane/butane canisters that are sold for backpacking stoves.
Propane is better in colder weather (if gets less efficient than white gas) than the mixed fuel canisters.
The drawback is that propane has to be pressurized more and the fuel canisters are much heavier than the ones you use for your SnoPeak/JetBoil/etc. They are fine for car camping, but a bit heavier than most backpackers want to carry.
In the end, since you are going to springer mtn, a canister (or even an alchy stove) will be just fine. Sleep with the canister, and try to find one with more propane and less butane as that mix will burn hotter and better even as the canister gets more used.
Good luck!
