I don't want to hijack your thread, but this is an issue I've been working on recently. I would need to treat at least two gallons a day, and where I hike recently it pretty much has to be all at once. Optimally, I could treat a quart and then drink it as I move to the next water source, but things have been so very dry recently that it has forced me to change methods. I've got a Hiker Pro, though it needs a new cartridge. The Sawyer Mini is about a third of the price, but I'm worried that it will be a major pain in the butt to treat all that water all at once.

What am I missing?
