The reason I've stayed with a canister stove is that while breakfast is just a quick boil, and lunch is not cooked, dinner is pasta or rice with freeze dried meat that takes 15-20 minutes on low boil to become soft and good-tasting; and the sauce, spice and dried veggie mix added takes another 5-10 minutes of simmering. With enough water for a couple cups of tea or other hot drink, the Shelties' kibble, and sterilizing the utensils and dog dishes, that all requires over a quart of water to be boiled. The payoff is that the dinners really taste good, and unlike all freeze-dried, provide plenty of energy for the next day's hike.
The weight of the full Coleman canister is around 13 oz when full, and the Ti Snowpeak Gigapower stove with plastic canister stand and Ti burner windscreen, around 3 oz, for a total of a little over a pound on the first day when the canister is full. That lasts for 6-7 days, at which point a resupply cache is reached on the route, with a stay at a lodge or cabin if convenient.
This system requires the ability to regulate the simmer or boil, and the canister seems to excell in that, especially a higher altitudes of 10-12K feet. The concern about the focused flame on the stove never proved a problem. So the weight runs from a pound down to less than a half pound, and the food is delicious, carefully mixed and packaged at home with the best ingredients. Very clean burning with easy cleanup.
Unforunately, the canisters have around doubled in price at Walmart; but enough were purchased when they were $2.50 US to last for a while still.
But I can easily see why the alcohol would work better for long distance treks, as opposed to a total of three or four weeks in the summer.
