Just ran across this tidbit lookingat a survey of Pacific Crest Trail hikers - the last comment is fitting for this thread and its discussion of the Sawyer filter:

Go lighter.
More expensive doesn’t mean better.
Get a good down sleeping bag.
Good gear is worth the investment.
You will get sick of your Sawyer Squeeze.

I have no experience with the Sawyer line(Iam a "boil it"guy myself - the other comments make good sense too....

These were people who were hiking for months on end,not just using their gear intermittently.
