I don't think the question has ever been strength. It's side to side stiffness. The 1st gen frame moved with you like it was a part of you. The K2 took away that movement, and I don't like it nearly as much as the 1st gen frame. Sounds like this K3 frame is in between, but that movement is coming from belt attachment points and what not. I miss the side stabilizing straps from the 1st gen. Lots of K2 owners said the same thing, pack felt too tippy side to side because those straps were removed. Interesting to see what they look like, but late July early August is way too late for me to think about a new pack. My hunts start early August, spring bear starts next week. Too late in the cycle to get one of these for this fall.
