You are of course correct in your assessment of superior 3-D from porro glasses. The Swift of mine has it big time. That 3-D efect in my Nighthawk is its most outstanding feature. I really thought the 3-D porro effect would help the 9x35 more than it does. With the binoculars I have, the brightness and contrast improvement in the view seems to cancel out the 3-D effect when you're watching a magpie. It probably is also a pretty fair statement of newer coatings and application technology too.
You are also right about the endemic rocker effect with the fast focus modern roof. My Eaglet has that and at first I thought it would drive me nuts. But I got used to it. I now have glasses that go from 1 turn to two full turns of the focus knob. I hardly notice now. One fault I find with the Eaglet is that it takes too litle effort to make it move, especially when you don't necessarily want it to.
The Viper is a whole different beast from the Diamondback. Look at both side by side and you may not be willing to go back to the Diamondback, unless your use is astronomy, whereby the FOV may decide the issue. The Viper and Eaglet really compare visually more toward the $1,000 end of the optics spectrum than they do to the upper end mid price roofs.
As to my 9x35, the only number is 14554 on the objective end of the hinge with the Leupold logo. On the ocular end of the hinge with the IP measurement is M2.
