I tried Retro 80s (35mm and 120) in some different developers, Rodinal and Xtol among them; it worked out well in all of them. Contrast builds up quickly, you'll have to watch that.

This film is very different from APX 100- different tonality (not as nice but that's just me), grain (less of it), sharpness (sharper), and a different base as well (polyester vs. acetate, watch out for light piping). Just a completely different film.
