Re: Pack Choice
I have used a Kifaru on many mountain backpacking hunts and would highly reccomend them. I don't have a lot of experience with other high end packs so I don't have a feel for how Kifaru compares to the other packs mentioned.
At the very least go to Kifaru's web site and order the gun bearer system. It is less than $50 (I think) and worth many times that when carrying a rifle in rough country (double or triple that if it is heavy cannon us LR types are known to carry). It keeps the rifle secure and puts the weight on your hips rather than your shoulder. It can be put on any brand of pack.
