Q: Canister fuel of White gas?

From official Denali source: "White gas stoves have been a staple on Denali for decades and they continue to provide reliable performance in cold weather and at high altitude...Cartridge stoves are sometimes used on Denali, but they don't tend to perform as well in cold conditions, the cartridges are not as widely available, and they aren't as efficient for making large batches of water and food"

For many years I used to be a fan of MSR Whisperlite white-gas stove, in fact we brought two of those for our first Denali attempt in 2018, but after I saw Reactor in use, I changed my mind.

So now we take Reactor as main stove, which is cartridge-based. From manufacturer: "Produces consistent heat output. The burner operates near max at lower fuel pressures and improves output in colder temperatures. An internal regulator equalizes pressure for consistent boil times throughout the life of a canister." By the way, both Whisperlite and Reactor are made by the same company, MSR.

Hard to agree that it will not be "..as efficient for making large batches of water..". I have tested Reactor in different environments: bringing 1L water to boil at sea level, at -20°C cold, at 3,000m altitude, after freezing at home fridge' freezer and it always outperformed white gas stove - both in speed and fuel consumption. Besides, only Reactor has windproof burner. Priming white gas stove inside tent or/and in stormy weather is a poor idea, when Reactor will work just fine.

So, the MAIN question is: will our Reactor work at High Camp at 5,259m / 17K (if we ever make it there)?
