The Fuji is a lot more capable aerobatic machine than the aerobatic Musketeer. A few years ago I spoke to a friend who had 2 or 3 old Fuji airframes in his hangar - some parts are unobtainable these days - that would be my biggest concern with a type no longer supported and with only a very small number throughout the world.
