I might be missing something here, but I recall reading about Kifaru, Mystery Ranch and McHale that their load distributions moved weight to your hips to bear a good part of the weight. Lowering the center of gravity of the pack making it more comfortable for heavy loads. Just thinking out loud, but it seems that your lower back is the last place you would want bearing your pack weight.
Ya..I saw that too. Im pretty sure its just worded wrong.
