Glycin is supposed to be good for stand development, but my own experiments with it have not shown it to provide any advantage over straight Pyrocat-HD. In fact, for a non-staining developer I have gotten much better results with Rodinal.
BTW, what times did you use for TMY? And what process are you printing with? I just developed some sixty sheets of TMY 5X7 using extreme minimal agitation with the 1:1:150 dilution of Pyrocat-HD and the contrast of most of the negatives is perfect for my printing with long exposure scale processes.
