My old Camp Trails pack is tired. I need to replace it for 2012. I have been examining both the Barneys (similar to my existing pack) and the Kifaru UL. Now I am familiar with the merits of an external frame system as I've used one for 10 years. But shaving off 3-4 lbs initially from your pack weight with the Kifaru has appeal to me. But I have no prior experience with an internal frame. I need a pack that can handle a 125-130 lb load if needed, although I try to go in at 50 lbs or under.
For those with experience with these two makes of packs, please help guide me in my purchasing decision. Neither are inexpensive so I wish to make the best decision possible.
