Was using Delta 100 & HP5 but just discovered Agrfa's APX100.I think the APX would be my choice for 35mm.
In my beat up old Yashica, it would likely be a Delta. I would leave the choice up to which ever washed up on the beach of the deserted isle with me.
As for developers, I have only used 3. Ilford S, Ilford HC and what ever was in the container at the night class I took. (I think it was D-76, but was told they switched occasionally). My choice (of the 3) would be Ilford HC.
