So, in order to get proper load lifter placement on the NICE frame, one must go with the 6500. The CC or a long bow loaded with heavy gold bars, when placed on the NICE frame, places them too low for what is considered heavy load carrying comfort. Got it. Why not just place the load lifter straps on the NICE frame the same for all pack models and just have them hook up on the NICE frame and always be perfect.
