I hate the harness on the AGC. I like my pouch high and tight. The AGC hangs down around yer belly button, while the Marsupial is like Goldilocks bear, 'juust riiight'..... That said, I like the AGC pouch when I hook it direct to the backpack shoulder straps and get it up where I like it, I just pitch the [bleep] harness in the pack.....
