I had the chance to see them at this year's Shot Show in Orlando, FL. I thought they looked good and didn't seem as heavy as the previous front focus design. Also now that they are side focus the front bell is not as large and I think one could use shorter rings to mount them with.
The side focus knob is small - not like a Night Force or similar designs. That's + and -. All this said, I almost wished I would have waited on the new design. I bought a 8x32 BD last year and it IS big and heavy. The new design seems less so.
