I shot one roll of Pan-X that I can recall, and might have done a second some time. I just never really have use for film that slow. Even with PanF+ I develop it in Diafine, partly for the compensating action which works well with that film but also for a slight speed boost.
How did the scale of Pan-X compare to, say, Agfapan 25? That film lasted a lot longer and seems to have been widely loved. If it was as good as Agfapan 100 I can understand the love for those who can live with or prefer the speed. If Agfapan 25 or Efke 25 were anywhere close, resurrecting something similar, possibly via Adox, seems not too unreasonable a thing to hope for.
