Both the Orwo 74 as a 400 iso and the Orwo UN 54 as a 100 iso work well. The Orwo 74 is in some ways a better emulsion than the XX, a true 400 iso film and works very well in MQ developers like D76/ID 11 etc.
The Orwo UN 54 is my "summer time" emulsion - maybe not as good as the old EK 5321 Kodak +X movie stock, sadly discontinued though, but not far off. I stocked up on it last year 1600 ft and still have 1200 ft left. I have enough XX left for a while (6000 ft), but when that is done I am switching to Orwo 74.
TriX is still a great film - but when prices start climbing too high, I look for alternatives. I go through 500+ rolls a year and that is significant money. Still some Arista 400 Premium in the freezer (2-300 rolls) which I bought when it was $ 2.09/roll!
There is also a "dogs breakfast" of 100ft rolls in the freezer, ranging from Technical Pan to Fuji Presto 400 - and a small hoard of Neopan 1600 (i think about 40 rolls). I am set for the next 2-3 years - but I will start stocking up in 12-18 month. When I can see the back wall of the freezer - I get nervous!
