surely old pac lab is still processing old tri-x?
as for the difference in the ASA ratng: that would be because B&W film is
more sensitive to the blue part of the spectrum; expose it under tungsten
light, and you've effectively reduced the sensitivity of your film, all
other things being equal; to compensate for this you're asked to rate your
film at 160 instead of 200, which would then compel you to open up your
aperture about 1/3 of a stop.
