It may be that people who like the more idiosyncratic things about older films (like large grain) are most likely to be disappointed by the extraordinary qualities of T-Max and the Delta films and Acros.

In B & W I shoot Plus-X and T-Max 400. I like the differences, and I'll miss Plus-X when I've used up what I already have, but I'm more likely to transition to T-Max 100 than FP4+.

Not that FP4+ isn't great film.
