I’m glad you found peace! How do you like the screen movement?
I've spent some time paying more attention to the screen movement. For me, whether on a tripod or kneeling at an odd angle, while there are a few minor restrictions to perfect positioning, the screen movement is fine in about 90% of cases. (And I like how the tips at the gap for the screen are beveled better than on the Kirk.)
But that is for stills. For video, I don't have much experience, though I did use the flippy screen to take some video of how lens IS components shift about. I placed the camera on a tripod, pointing down, and I had to come around to the front of the setup to hold and move the subject. I was able to move the screen so it was very easy to watch as the video recorded.
Sorry, but that L-plate you showed is way more complicated than I want full-time on my camera for stills, and I'd rather have a little restriction of the flip screen than any restriction around the lens barrel. (But I do like the option to protect the ports!)
Truly, the ergonomics of the R5/R6 L-plate make it a great choice for those who want to mount it and forget it. "Elegant" is the single word I go with.
