My personal experience is that Tri-X 320 (320TXP) does well in HC-110 and D-76. However, Tri-X 400 (400TX) does not do so well in HC-110 as I find it more contrasty and harder to control, so I use D-76 when developing this film. Most of the time when Ansel Adams is referring to Tri-X, it is actually a formulation of Tri-X which hasn't been made in decades (pre-320TXP, even though it was a 320 speed film as well); thus, people use the modern formulation with his times and get different results.

I would recommend the D-76 with 400TX, much more manageable and versatile.
