Faith. Good luck with that approach. But you aren't actually saving money that way if you're having so many problems. I've never had scratches with Arista Litho myself, but don't use it all that often, and mainly only as a high contrast lith film in relation to highlight masks, not soft contrast masks. But not too long ago I did use some for a succesful moderate contrast application. I don't know if any significant changes to it have transpired or not. What country of manufacture is printed on the box? Linear scratch patterns do sound like a cutting line issue. So I hope you get some kind of answer from Freestyle.
As far as what others might have said or briefly experimented with, Ctein personally stockpiled and used Kodak Pan Masking film, and almost entirely in relation to dye transfer printing. That film was equivalent to Plus X Pan sheet film minus the anti-halation layer. Nobody back then did contrast masks with Kodalith, or even Tech Pan, because there were so much more cooperative films. But if you are budget-constrained to use an ortho litho film, I wouldn't give up on Arista quite yet. Maybe they can send you a replacement box to test.
