"1. protect from viruses (tiniest of baddies)"
Not Always, most of the time the water will be good, but you never know by looks anyway. Some places I go, I will want to kill this as well.
"2. protect from bacteria (medium size baddies)"
Same as above, but would be good.
"3. protect from protozoa (large size baddies)"
I assume that if I remove no 2 than I remove no 3.
"1. hate waiting (or don't mind waiting)"
Usually I will be prepaired and be doing this during the night. But if I'm on the trail, I would prefer not to have to wait that long.
"2. hate pumping (or not)"
Happy to Pump.
"3. hate weight"
Dont we all? Not as much as some people, also will be split between 2 so that helps.
