I was very fond of Legacy Pro films (re-branded B&W Neopan). Best film ever in every sense.
I only have one 100' of 400 left. So I managed to get a photo retail clerk to inquire about expired Neopan bulk films. We never know.
If this request doesn't work, I will go for Fomapan which is a nicer film than Tri-X or Arista Premium.
