In my (limited) experience, no. The problem is more that the shoulder straps connect too low on the bag. On my Gregory pack the shoulder straps connect to the bag above my shoulders. On the G4 the connection point is below the shoulders. To fix this would require either connecting the shoulder straps higher on the bag, or the belt lower on the bag, so that the straps connect above shoulder height. I'm not sure how that would affect the fit, since there is no frame to the pack.
Life should not be a journey to the grave with the intent of arriving safely in a well preserved body, but to skid in broadside, thoroughly used up, worn out, and loudly proclaiming Wow! What a Ride!
