  Tri-X sheet film has a similar tonal curve to Plus-X
although not quite as extreme. There is really no way of
duplicating the effect of the film curve by choice of
developers although they may have some effect.
  Look at the published curves for Tri-X (or Plus-X is the
old data sheets are still on the Kodak web site) and compare
them to T-Max 100 or 400, which have relativelly short toes
and long straight line sections. If you plot where the
different gray tones (or Zone system zones) fall you will
see why they look different.
  AFAIK, Tri-X sheet film will continue in production.
  The roll film and 35mm versions of both Tri-X and Plus-X
have medium toe characteristics, quite different from the
sheet film versions.
