ok, my vapor trail weighs in at 28 pounds fully loaded and ready for the trail. i wore it last night for a couple of hours and walked to work (1.1 miles) with it this morning. i am having an issue with my right shoulder. it feels as if the strap is slowing the circulation in my right arm. i adjusted it several ways and it feels better but it's still not totally comfortable. is comfort something you sacrifice for the weight loss ? maybe i am being overly analytical and trying to find fault in the pack. also my food bag was at the very top so that weight is actually extended slighty above the inside of the pack. i am going to try lowering it towards the center and putting lighter items on top of it. any other suggestions or ideas ?
