Thank you all for the replies. It all sounds like good advice. I like the idea being able to adjust the suspension. I have been measured several times and I am exactly in between a medium and a large. I think my torso measures 19.5 if I remember correctly so in addition to the volume issue, I have the pack size issue. When I initially tried out packs, I did have them weighted to 25 lbs but I had never worn a pack, so I had no point of reference. I have had some days with my Flash 50 where I didn't even know it was on, and others days where it felt like the cross I had to bear. I know longer keep my hydration bladder in the pocket against my back. I could really feel it and was very uncomfortable. Each time I take a trip, I am trying to make notes of what works and what doesn't work.

Thanks again,

Dave
