Consider this a suggestion. I suggest making the speed ring as a one piece sheetmetal stamping with a spill kill reflector as part of the base. My present spill kills won't fit with the speed rings.

That is more or less the way they are currently constructed. With the new design, the deeper design of the PLMR/7UR would keep the umbrella from being completely filled at optimum focus.
