I shoot a lot of Fomapan 100 in bulk rolls, mainly because it's inexpensive and I like the classic look. I'm in a sunny environment, so I don't need the speed. Haven't had any QC issues with Fomapan, except for 100' of Foma 200 which was badder then bad. To be fair, I ran into a brick of Tri-X about the same time which was equally bad. Both slightly out of date, both cold stored. Being the cheap guy, I forced myself to shoot most of it, fooling around with different developers, trying to make them look less bad. Nothing really worked and I wasted a lot of time.
I do experiment with some oddball films. Currently struggling with Eastman 5234, an iso 6 copy film.
Honestly, I just should pay up and get the good stuff, something Delta 100 or FP4. Never been a big Kodak fan after the demise of plus-x, though I appreciate the flexibility of Tri-X and it looks good in Diafine. Still have a half dozen couple bricks of EFKE in the freezer. Don't know why I'm saving it.
Mostly used Rodinal and HC-110 due to self life, but in the last year or so I've tried some others -- Diafine (ok), Clayton F76 (very nice), Adox, FX9 (very nice), Fomadon LQR (yuk!). I don't like powders.
Nice to still have choices! Something the digital crowd doesn't have, unless they drop on a different lens.
