Good job Scott and Nevada for the detailed review. It is interesting that you say the Metcalf allows for the most organization, but I find myself wanting MORE organization than the metcalf has. This is usually only when I'm not using the daypack lid with it during day hunts though. My biggest beef with the metcalf (MR Nice packs) is the base weight. All trade offs, I suppose. Weight, organization, and durability. Hard to do all and keep the weight down... All four packs look like they'd be great packs!
