Like some other posters, I can only recommend the j104. The new dragonfly is similar with a detachable top pocket, but is way more expensive. This pack is beyond burly. I have packed out 5 bulls, 4 mulies, and 2 pronghorns with mine. It will take anything you throw at it ... anything! Eberlestock has an excellent no questions warranty and gaurantees the bag will carry anything you can strap in or on it and get it on your back. This pack is the single best piece of gear I have. I also have the Jim Horn Canadian pack, and it is awesome, but the j104 is in its own league. I see some questions about the Kifaru's rifle carrier. There are no questions about the j104's rifle scabbord, I swung around a corner of a trail to come face-to-face with a small herd of elk last season. With just a grasp of the stock, my rifle was at the ready in my hands, silently, with my j104 still secured on my back. The scabbord holds my sendero with a 6.5-20 X 50 mark 4 nicely. Since I've started using my j104 (3 seasons) 6 of my hard-hunting friends are sporting Eberlestock packs (j104 and j107). It is a great pack that becomes a greater pack when you load it with meat, cape, and antlers.
