I really like the looks of the Mystery ranch nice 6500 pack. An outfitter buddy of mine bought one and says it packs a heavy load real well but it's heavy as hell when you're day hunting without much in the pack. They look heavy to me as well, quite heavy. All I have used for backpack hunts to date is a hippy pack (osprey) as they seem to be lighter and well designed. The "hunting" packs haven't quite sold me yet, but I am eyeing the Mystery Ranch. I would like to hear some responses from some people who have been using various packs and what they think after using them for a few miles.
