Check out seek outside packs. They look a little goofy at first but the set up is perfect for a glass heavy hunter. I use the peregrine and have packed a lot of meat and camps with it. It's perfect for day hunting and can do a 3 day with aplomb. The frame and rigging is some of the comfiest I have ever used. I would also look hard at kifaru hellbender if you wan to only be able to do a daypack/meat carrying option. My buddy just got one and their meat tray system is unbelievably simple and easy. If they weren't so expensive I would buy one for sure.
