OK, that is one reason for our different results: I do want a straight
line
curve for all my work. If I do not want detail in the shadows (rare), I
can
reduce exposure and it will essentially drop off altogether.

That is the second reason for our different results. For 35mm work, Tri-X
has an acceptable curve shape. But 4164 Tri-X is so different that it
should
not even have the same name as the 35mm stuff.
