Recommend film for shooting at around 800 speed and developing in HC-110

If you go by the Kodak Technical Data sheet (F-4017) For Tri-X you can shoot it 1 stop underexposed ISO800 and process that same as shot at ISO400. Would suggest dilution H due to the rather short development time provided by dilution B.

Also, it's general consensus the published HC110B time for that is wrong- most people use 6.5 min at 68 deg F
