First of all, let me suggest that you check the archives, this subject
comes up quite often (and thus the archives should be very helpful). It
seems almost everyone on the list has a different method. My favorite is
(like Terry's) FP-4. I would mention that it is available through Photo
Warehouse in sizes up to 20x24 inches (they won't/can't call it FP-4, they
call it "Pan Portrait". Don't ask me, ask the lawyers!).

Both Terry and I are using a variation on the Phil Davis article you
mentioned. Davis's point should have been that a modern "strait line" film
developed in paper developer will give appropriate contrast. Tri-X is an
older, less strait line film. Because of it's shoulder, I dought you will
be happy with it for enlarged negs. HP-5, T-max 100, T-max400, or FP-4
will work. One big advantage of the FP-4 is that it is available BIG.

I haven't tried Terry's "Universal" developer, I develop mine for 5 minutes
in HC-110 (30ml per liter, dilution "B"??) then do a second development in
Zone 6 paper developer (Dektol would do fine) for from 45 seconds to 3
minutes depending on the contrast I need.

If you are going to shoot film for enlarged negs (and you are not shooting
in extreme contrast situations) try shooting E-6 color transparencies.
That way you already have a "positive", and the enlarged neg is only a one
step process. A side benefit is that you can do some color filtering in
the enlarging process to shift values.

I believe Calumet sells Kodak professional copy film in 8x10.
