Hi Nate, hope you are doing well, and a belated thank you for the manuals.
In the past I have had good results making digital inter-negatives. This would be my suggestion, if you are set up for it. If not, many years ago I used Agfa N31P copy film with HC110 diluted 1:15, which came out of Jerry Spagnoli’s 2002 manual. I am sure the Agfa film is long gone, but perhaps someone knows of a replacement?
