Im about to purchase a kifaru tactical frame and i have questions on the frame height and loadlifter function. Besides the fit of based on torso length how important is loadlifter height over the shoulder? im wanting to use this pack for all my hinting from eastern dayhunts to elk hunts. I dont really want the load lifters sticking up to far and catching brush. Alot of guys that whitetail hunt use a 22” frame and its even with top of the shoulders, but does this keep you from packing out heavy loads? I dont really understand the function and importance of the load lifters.
