What about the MM77? Almost in the 80mm class but still very light. And you can use the fixed HDF e/ps to get lovely wide fovs.

I own MM4 and have owned the Swarovski ATS 65 and currently own ATS80. There's really very little between them except weight. And light gathering for the 80mm which is why I use it in winter if not carrying it far.

Any gain in magnification is usually countered by heat haze and the like. Doe to this I can seldom see more in the Swarovski at 60x compared to the MM4 at 45x. I can ID and enjoy any bird with the MM4.

I guess what I'm saying is, the differences are only noticeable when comparing these scopes side by side.
