Ok..i just checked my Harness..the bar is in the same place but it is a wider/taller piece of metal, so it holds the pack a little higher. I suppose this could be the issue. Also the hooks that were on my pack seem more shallow than the ones on the Heilman photos. So it may be the combination of the 2 making it slightly off. I may be able to replace th bar with a thinner one and just raise the lower hooks by 1/2" i think that mnay solve the issue.
Mind you this isnt a "problem" everything is comfy and all, i just noticed with these 2 photos that you dont see the harness at all on the promo pic....and my OCD kicked in LOL
Oh and Aaron, going by that ESB promo pic, your pack is sitting to high, and mine a little low lol
