Lol....my experience is the exact opposite of Volker, I shoot TMX and TMY exclusively and I have found it to be a wondeful film. I don't know why Volker has problems with accutance but my negatives have sharpness that people comment on. Also I routinely shoot f16 f22 with my hassy and I have never seen this diffraction problem, for me the f16 and f22 are the best openings, of course I do use a tripod. BTW I have a 50 an 80 and a 180, all of them show exceptional sharpness at this stops.(posted 8331 days ago)are the tubular films more difficult to use? sure, and therein may lie Volker's problem, but once you get the hang of it the T max films are wonderful.
as to refixing your cut negs, buy one of those paper separators at an office depot, fill a container that will cover this separator and put the strip in each slot....should be a piece of cake. Good luck!
