BW400CN is capable of great results but is orange masked to print better on RA4 paper in automated machines. XP2 Super is a fantastic film without the masking, to print more easily on regular black and white paper.

There is a professional Tri-X, TXP 320, P for Professional, now available only in sheets but previously available in 120 though no more. It's a great film but quite different from TXT 400.
