What's the main objection to Ilford FP4 if any?
If you really want to become an expert at negative retouching, Efke is your baby. FP4 comes out clean 99.9 % of the time, when it happens it's dust not defective film.
The same is true of Kodak films.
Any film with ongoing problems just isn't a bargain.
