I had a Genio FF before the BFD and this device uses hard plastic rings as known from ARRI, Chrosziel and others that can be changed faster than the strips coming with the BFD. I have followed a thread here supplying rings that are cut and so in my eyes will slide and need fastening by the screw in the BFD. So no match here.
Today I was checking in at Camtec and after heavy brainwork of the two of us Markus Bernhard made me a couple of rings that 100% match what I have been looking for to make my AC happy. The rings are a bit wider than the stripes and I initially thought they might make the pulling uneasier but that was not the case. They fit on the BFD wihout any modification of the device. You simply use the same screw to secure the ring. This can be seen very nicely on the picture I enclose. One other good thing too, is that regular 19mm tape fits perfectly on the rings.
If any of you guys have ideas of mods I would like to know.
