I prefer graded papers in general for PMK negs and in general for that matter (except for particular negs that benefit from split grade printing or burning/dodging with different grades). The theory is that PMK stain will reduce contrast in the highlights, since it is yellow green and increases proportionally with silver density. For the right neg, it may work, so I have a whole lot of boxes of paper, VC and graded for enlarging and Azo grades 2 and 3 for contact printing.
