Just for further clarification, ABC Pyro at the 1:1:1:7 dilution gives more contrast for a given time of development than eiher Rollo Pyro or Pyrocat-HD at the recommended dilutions.

Rollo Pyro at 2:4:100 and Pyrocat-HD at 2:2:100 give virtually idential contrast for the same time of development with all of the films I have tested.
