For the guys that have run this pack, what have you had to do to get it "dialed in"
For me I only had to the initial sizing. I used the Krux frame and Approach bag last year to haul a Mtn Goat, two elk, and a mule deer. This was all with the one piece belt.
I changed to the three piece belt, belt pulls and added the Sky 7400 bag. I just got back from a week of backpacking with the 7400 and three piece belt. I did find that after having to carry a second persons pack, who was struggling. That I needed to adjust the belt pulls so I could tighten the belt more without hitting the belt pulls.
I have found the Stone Glacier to be one of the easiest packs to get fit to me.
