I have the Empire 09 ZN Liquid 4 + 7 Hinge Harness Pack Acid. It is really great, the one I ran with at the last game. The cool part about the pack is you can un-velcro the pods while your wearing it and fill them without having to reach behind you. If you wanted to see this one let me know and I'll bring it over for you to look at.
I almost bought this one, to go with my tank cover.
