That's some pretty impressive load carrying :O Do the studies also show the effect of carrying loads like that on the body or just that it's efficient? :D

It cant be good over the long term. Its just much more efficient to carry directly on the spine, it is similar in Africa where they balance things on their head. It seems 80kg on your head is about 40kg on your shoulders; neither would be very pleasant.
