Remember the tale of the princess that could feel a pea under her mattress? In the same vein... how much weight can you add to your pack weight and tell a difference?? I mean a point where it begins to bother you. Also any thoughts as to the "sweet spot" of pack weight to comfort (less fiddle fart time, temperature range cushion,ect)and list choices that seam to make this comfort most noticeable.
I feel stuck at 8.5 -10 lb base. Every time I attempt to go lighter I experience a freak temperature drop (in Aug), wind driven rain, need the repair kit (blown shoe, pack strap).
