1- I have a Hennessey Hammock that I like. The Clark looks good too, though
2- Not interested in Jet Boil, I have my trusty Trangia. I'll stick with that.
3- The Lifesaver, however, sounds very interesting. I have a decent water filter, but each filter only does 200 gallons vs. the 1000+ gallons with a standard Lifesaver. My filter doesn't filter out viruses and the filter doesn't shut off when it's used up. The Lifesaver seems like a great tool to have around in the event of a natural disaster, in addition to the camping uses you've already mentioned.
