I don't want to knock Tri-X. For atmosphere its wonderful, but for high resolution data recording it is a lot less wonderful and that is what I do. Sadly Delta 400 has been discontinued in 220 and Tri-X is the only replacement I have found so far. I know I can get 120, but changing film every 10 shots in a very cramped light aircraft really isn't practical when I am often taking 3-400 pictures in a three hour flight.
