I have both TMY-2 and TX400, FP4+, GP3, Pan F+ in b&w and some others.

I was wondering if there was something to it, like plenty of contrast in the blacks, but easily distinguishable shadow detail, and softer/smoother highlights and midtones from the cubic grain highlight retention (less sensitive) where the flat grain loses detail there (but still contributes to density thus softer contrast?)? etc?
