Every single culture in history that portaged heavy loads on foot used tumplines, with the weight pressing directly down on the spinal column for maximum efficiency. The hips were only used to carry lightweight tools and weapons, maybe a #3 sword at the absolute most.

I don't use hip straps because my hips are where I carry my gun and survival knife. I use tumplines for heavy loads like all of our ancestors did, but generally my camping loads are not heavy enough to even necessitate this. Either way hip straps suck and mean you don't know how your own body works and signals that you are probably unarmed, just maximum gay.
