The serving size is 8oz at a time, haha. I didn't drink this one, just came across an empty. I don't believe they still make them. :(
I have historically carried 1 x 1.5l Poland Springs bottle and 1 x 2l Platypus. I have done this because I ~feel~ like I consume a lot of water on the trail and I have used Chlorine Dioxide tablets. Of course it all depends on the trail and water availability, but if water sources are plentiful enough and either a) I'm not as worried about beasites in water sources or b) I carry a Steripen that doesn't add too much weight to my pack weight, I could conceivably carry less weight in that I won't have to carry as much water.
So I'd always have a 2l platy with me in addition to the 32oz stove/Monster BFC.
Not sure what you mean by wire? I think I can put the can directly into a side pocket, replacing a water bottle. At worst, the can will need to go into a rice cakes sleeve if I use Esbit tabs (gets sooty).
