After researching my pack options I have decided that I want an EXO. Now I can't decide on size. It seems that both the 2000 and 3500 are much larger than what they are rated for. I don't ever pack in a camp and only need a day pack that can handle a bow, spotter, tripod, and gear/food for mule deer day hunts. I am leaning toward the 2000 but the weight difference between both sizes is minimal and the 3500 seems to compress down to nothing. Does anyone have the 2000 that can shed some light on this?
