I heard people mention get a Barney's pack but should it be internal frame or external frame? Which is best for sheep hunting?
IMHO, NO, no way! My partner tried an internal (one of the more common ones often mentioned on the board) and he said it sucked. They keep you bent over too much while walking. Get an external frame pack and tighten up the belt so your hips take most of the weight. You can then loosen the shoulder straps to "snug" to take some of the weight off them. Much easier on you.
