I was in the exact same spot you were in until i called Aron from Kifaru. I have seen a lot of his videos and it seems like he knows what he is talking about from experience and not just designing a "new" pack/frame system to fix previous problems from years before. I got my new DT1 on Christmas and am very very impressed with the fit and different adjustments you can make with the pack. For instance, one of my shoulders sits a little higher than the other and i was able to individually adjust the torso length and shoulder strap length to fit exactly how i needed for my body. I am also 6'6" and needed a pack that would fit me. Aron's hunting partner is 6'10", and he gets good lift from there packs and so do I. I loaded it up with 100LBS of sand and the load lifters worked really good and the weight felt as comfortable as 107LBS would feel. Now i am trying to figure out how i want to run the pouches and attach my bow and stuff like that. I am open to you coming over and trying my pack out if you want. I know it can be tough to spend that much money before you even try it on.
