I would agree on using the phil ones. They get drug thru the dirt, etc, and they are heavy duty, but not real heavy. You can save a lot of personal weight with your crew by making sure they have decent personal packs, bags, sleeping pads, right amount of clothes, etc.
But the organizational point brought up is valid. We made sure to pack the bags by meal type before hanging, and the next breakfast was on top of the breakfast bag. We had full crew of 13, and 4 days food starting out, think we had 7 very full bags plus the oops bag, that was a lot to lift.
