Well here's the question then?? How is the best way to figure out fit of a heavy load hauler w/ day pack, other than years of painful experimentation? Already done the pain thing and I'm not interested in doing it again or any more. My torso measurement is 20". The ILBE has no reference to torso sizing that I can find? I am having a very hard time thinking about paying $400-$600 for a pack!!!

Cheers,
