I thought so, what these fellows do seems to be more in the realm of a week and longer with a backpack which isn't common at all here in Australia.
Most of us here set up a base camp and pack out from there for a night or two, which is why we tend to use heavier ex-military canvas tents and stretchers (or a truck tarp). A few of the sambar hunters do what these fellows are doing but not for the length of time.
Your questions may be better aired in the general hunting section...but these fellows certainly know a bucket load about light gear, stuff I have never even heard about.
