Getting back into backpacking and was looking into a new pack. Used an old ILBE for a few years and want to upgrade. Been looking at some of the larger Mystery Ranch packs, as I have a Sawtooth for hunting that I really like. Mostly looking at weekend trips and nothing more than 4-5 nights. Are the hunting style backpacks worth the extra money or are you better off with Osprey, Gregory, Kelty type gear? Thanks
