As an update, I decided to make a few lith prints with this paper earlier this week. Addition of benzotriazole and exposure times around 30 seconds at f/2.8 gave outstanding results - clean whites, very good blacks - and it's absolutely beautiful in selenium. I did get an extremely gritty pattern of what looks like fog in some areas, which was at first a mild nuisance, but it lends itself to certain night scenes on pushed Tri-X and TMZ. Which happens to describe most of my negatives. Thanks, all!
