>With the low volume kit(and I really like that concept a lot), an Esbit wing stove and fuel would be easier to stow and might make for more pot options.
Sgt. Rock's Ion kit (1.2 oz) includes stove, pot stand, windscreen, base reflector and stuff sack. That's less than my Esbit wing stove alone (1.3 oz), although the BPL Ti wing stove is lighter than mine. Fuel wouldn't be very heavy either way, as I'd carry 2 fl oz of alcohol v. two Esbit tabs.
>Find a lumbar hydration bag with enough extra storage capacity
This is a lumbar pack, but I suppose it could be replaced. I'm afraid I might not have enough volume if I lost 1-2 liters of internal space, while the Tour has two 1-liter water pockets on the outside.
One reason for choosing the UV Aquastar over Aqua Mira is that I can sterilize water and drink it immediately. This way I can tank up at streams and still have 2 liters for dry camping, whereas with AM I wouldn't have as much left in camp. It also allows me to carry only 1 liter of water when streams are frequent, which is a weight savings of 2 pounds.
Equipment is always open to reconsideration, of course, and once I've got a stable kit I'll see if I can make system changes that save weight.

The largest cylinder is 700ml, and the weight unknown. I expect I'd have to add some plastic wrap to keep the water from leaking out through the threads. Anybody know the weight?
