I haven't ever owned one of the HDs so I cannot give an opinion on that. I've heard rumors that the 3-9x42s are made with HD glass but have never confirmed that... they are easily as bright and clear as a Leupold of similar magnification, though. I don't get hung up on "glass" very often.... because I don't observe game through my scope.
Total weight with the SS 3-9 up top is 8.6# with a Montana sling. Not too bad.
