Maybe I missed it, but I don't even see a mention of the BeFree bottles/systems. We switched to those and have not looked back as they are easy and inexpensive. Before that a Katadyn Hiker Pro,with hook up to fill bladder while bladder in pack. These days carrying smaller 2l bladder, extra 2l Platypus, and a Powerade bottle to mix drinks.
This. A BeFree filter and 2 CNOC 3L bags weighs about 7.5 oz. So much faster than Sawyer Minis.
