I tried a backpack and did not like it...
I like to run & gun, and I found a backpack to be inconvenient whilst trying to sit down quietly and quickly. Plus, if I want to get to something quickly (such as a call or binoculars) it becomes inconvenient as well...
I tried a well organized shoulder bag as well, but if the need arises to move quickly it flops about awkwardly unless you hold on to it.
Plus, I often have a decent walk back to the truck when I do get a bird, and stuffing it in the game bag is a good way to carry a bird, which you cannot do with a shoulder pack or backpack...
If I did not have access to a vest, I would rather carry a shoulder bag, because of the inconvenience of having to remove a backpack every time I sit against a tree.
