I currently have an Exo K2 5500 pack but have been thinking seriously about purchasing a K3 6400 bag as an upgrade and using it on the K2 frame. I have no experience with the K3 bags, but you know how it is when a newer model comes out, you convince yourself that you need it. For those of you that have used both, should I do it? What are the pros/cons?
