I didn't vote because there isn't a medium bag option. I prefer my setup to be modular. I have a small pouch with all my essential EDC in it that I transfer from bag to bag. Generally, I carry a Jumbo which I consider medium and it is rarely packed to the brim. I have room for some additional items should I need it. Other times when I have a larger load I carry a Bailey Works XL Pro Series Messenger bag which my EDC pouch fits inside. So I guess this post boils down to large and small with a modular approach.
