Has anyone tried developing 14x17 (or other ULF film) in hangers using gaseous burst agitation? I haven't tried it, but, in theory, it would seem to address most of the problems discussed here (streaking/bromide, uneven development, scratching, etc.). 14x17 is a very common size for x-ray film. So, hangers (both stainless steel and plastic) and tanks should be attainable.
