Others with more pertinent experience will likely chime in here.
As an aside, the purpose of Rollo Pyro was to slow down the oxidation of the pyro caused by the increased exposure to air caused by the rotary processing. Another way to deal with this is Bob Carnie's method of pouring out the developer halfway through development and replacing it with fresh. I believe he uses PMK.
