I have been using HC 110 for a long time as a black and white developer. Aside from its consistency, the base liquid lasts a long time, and I can thus use it as a one shot developer. I have been experimenting with different dilutions, and from the unofficial home page I found Ansel’s preferred dilution with TriX. His dilution was 1:119 (from memory). I decided to try something akin to it. I used 1:100 developed for 30 minutes. Agitate for the first 30 seconds, then 15 seconds every 3 minutes. This roll was shot at box speed. I quite like the results. Aside from the images of the dory that underexposed the expected shadow detail that Ansel drew from this dilution is evident. Again, I used the Pentax 645NII and 75mm lens, a combination that is immensely enjoyable.
