It really depends on what type of country you will be hunting. Well, maybe not. Probably any pack will do, but here in Idaho we have elk in the high mountains, thick trees, low valleys, sagebrush covered plains, and in our back yards at times. I would pick a pack most suitable for the type of terrain you will be hiking. Here in Southeast Idaho we just drive to where we are going and we don't get too far from our vehicle if we don't have to. I worked in a hospital for 4 years and I can't tell you how many guys died or had severe heart attacks because they were in bad shape for a deer or elk hunt.
So, my best advice for how to carry stuff in and out of a hunt is to take more thought and care of your permanent equipment than of anything detachable. If you are in bad shape when you get here you are in a world of hurt regardless of what pack you use. On the other hand, if you are in pretty good shape then most packs will do you just fine.
