I shoot Tri-X at 1200 in Diafine. Nothing I've done with TMY gives me results at that kind of speed that I like as well as the Tri-X/Diafine combo. At box speed I agree, TMY-2 is a superior film, but not in ways that matter to me very much or at all in medium format. If I were shooting 35mm to print larger than 8x10 it might, but I don't so it doesn't. I shoot TMY-2 in 4x5.
