It’s a tabular grain film more closely related to TMAX 100 or Delta 100 than Tri-X. If you haven’t tried a T grain film, I think Delta 100 is the cheapest of the 3 these days. I only shoot Delta 100 in 35mm and 4x5 lately, and I’ve never seen a huge difference between it and TMX or Acros. Acros does have the best reciprocity characteristics if that’s important.
