so far, my pack weighs 16.5 lbs MINUS food, water and fuel. how much more wt. will i end up adding to my pack? let's say for 4 days of food, carrying about 1.5 liters (i will likely have two 1 liter bottles, and i know the amt. of water varies during the day w/consumption and refill), and fuel is denatured alcohol. how much alcohol should one carry on average (for a pepsi stove)? i have a 20 oz. bottle, but i know i don't need that much, and that's pretty heavy. my goal is to keep my total pack wt. under 30 lbs. 25 lbs would be fantastic! (is that wishful thinking?) thank you, d
