I have the EXO K2 frame and 3500 bag. It is totally awesome. If you are only going to buy one buy the 3500. Otherwise the 2000 and 5500 would make a perfect pair IMO.
I really want to give the Exo a try. But I think for this year I'll probably end up sticking with my kuiu. As I have the 1850, and am planning a backpack hunt in which I'd buy just one of the larger kuiu bags. That way I'd have both sizes.
If I were to start from scratch with Exo, if need both bags and would be up to 700$ as opposed to a 200$ kuiu bag. And I want a spotting scope. Such a dilemma. First world problems
