They must have put in a lot of effort to avoid this pesky red sensitivity ... amazing that they got as high as ISO 80!
Seriously, they saved on red sensitizer, and brought nothing which can not be replicated with FP4+ or Delta 100 and a Wratten 44A filter. Yes, it's a specialty film - and for good reason. It will attract lots of "I've got to try this once!" folks, who then move on to the next "big thing".
Putting a Wratten 44A on FP4+ or Delta 100 lets me handle them under safe light and easily develop my inspection? Cool... I never knew how much magic they packed into wratten filters that they can change the properties of film even after you take it out of the camera...
