One more reason to not dedicate a frame to a spec. There have been a few ders which specifically were made to convert from a 52/3 BO position to a 50. IRD comes to mind.
One can file the BO slot lower if it's only a couple of Mms.
But the shifting issue claim makes me wonder about whether the full range of adjustments of the current der have been really explored. Andy
