Thats the reason I took advantage of the last time Fuji and Freestyle did a thing together, seriously stocked up on bulk rolls, got maybe 6-7 cases of 20, 2-3 at a time. Took a decently long time to empty out the freezer, but for less than 1.00 a roll I kept my film cost rock bottom.
I don't know whether the base on Legacy Pro 400 is different from Neopan 400. (I've only used the latter in 120) But, LP 400 is one of, if not the flattest drying film I've ever used. Also, if I forget the scissors when loading the tank, I can usually tear the film fairly cleanly with my fingers. Not with this.
