Bob and Frank D,
What is it that you find troublesome about double hinged pocket roofs? Do you have problems with cheap, floppy hinges (solution: buy a better grade of bino)? Or is it a matter of ergonomics? If the latter, perhaps the following observations might be of help.
I certainly have always appreciated the ergonomics of the Zeiss 8x20 Victory, which is an off-center single hinge design made for right handed/focusing users. It allows me a very solid/stable grip deep in the palm of my right hand, with plenty of room for and a comfortable grip shape for my (big) right thumb on the interior side of the right barrel, and positions my right index finger perfectly over the focus wheel. My left hand, placed overlapping and with thumb forward of my right thumb plays a seconday role in stabilization.
When I got the Leica 8x20 Ultravid BCL, my initial impression was of inferior ergonomics overall to the Zeiss Victory--didn't fit so firmly/comfortably/deeply in my palm, not quite enough room for my thumb, the distal joint of my thumb had a tendency to bonk into the diopter release button, and the reach to focus knob was actually too short such that I had to bend my finger and then focus using the end of the tip of my first finger (thus losing some focus precision compared with focusing using the "pad" of that finger). Inconsistency in precisely how much I opened the left versus right hinges to adjust the interpupillary distance made for a slightly different grip from day to day, making it harder to get accustomed to using the binos well enough that it did not require conscious attention. In particular, I wasn't as successful in getting the little exit pupils lined up to my eyes as quickly, perfectly, and reflexively as I could with the Zeiss each time I lifted them to my eyes for viewing.
By taking a lesson from my Zeiss Victory, I have now optimized my use of my Ultravids such that I now find their ergonomics just as good, if not better than the Zeiss. To set the interpupillary distance, rather than opening both sides approximately symmetrically, I now fully extend the right hinge before opening the left side to the correct overall adjustment. This simple act makes using the bino a completely different experience! It allows me to grip the Leica like I do the Zeiss, moves the diopter adjustment button out of the way of my thumb, extends the reach to the focus knob so that I can focus quickly and precisely with the pad of my right index finger, and makes the fit to my hand completely consistent from one use/day to the next such that I can now lift them to my eyes consistantly with perfection.
