Brush Developing with Pyrocat HD

[Mahler_one]

I noted on several sites allusions to using brush development with Pyrocat HD. Jorge is frequently noted as one with a special expertise in such "brush development", and has been a very valuable contributing member here in the past; Perhaps he is still here, and can comment. In addition, I wonder if anyone else on APUG has used brush development, and if so, might they be able to supply some details as to the "nuts and bolts"? I will be developing by inspection ( 8x10 sheets ) using Pyrocat HD and hope to try the "brush development" method to see how such compares with developing "sheets in trays". Bests, and thanks!
