GG Gorilla dimensions needed

Any Gorilla owners out there that would be willing to take some measurements on their pack? I'm between a medium and large on GG's sizing chart so I need more info. Here's what I'm looking for on both a medium and large:

-The distance from the shoulder strap attachment point to the TOP of the hip belt.

-The width (vertical distance) of the hip belt? Preferable a medium one but I imagine the sizes are similar if not the same for the width.

-The width and height (including extension collar) of the pack

I emailed these questions to Grant last night but wanted to see if I could find the answers here faster. Don't want to miss their end of the year sale!

Thanks for the help!
