I wasn't aware that any arista papers lithed properly. If it's rebranded Foma, only a couple of those will work. And when foma changed their gelatine, I think all their papers had non-lithable batches (a year or two back), but that was more globby blotchiness than (what looks like) coating errors on your example.
Keep in mind Freestyle has a great return policy, contact them, send them an example scan, they should refund or replace. Also, Foma 123 has been re-released in a lithable/bromoil-able emulsion as sort of a test project for Foma. It's available in 8x10 now, with 11x14 and 16x20 due June 30th. According to Freestyle, if it sells it may become a regular production item and has their money back guarantee as well.
Reports from the Facebook lith group have been promising, you might want to try a batch - I'm waiting for the larger sizes. Hopefully everyone will support this and Foma will make it regular stock or may do special batches.
