HC-110 is the developer of choice for many photographers that like to use older out-of-date film and get good negatives. HC-110 tends to minimize age fog, unlike D-76..which will show a little more fog with old film. I have Plus-X from1982 that is just fine, when developed in HC-110b. You should always presoak in water, and I think from personal experience, this is quite important with older film, as it "opens up" the pores of the emulsion, so to speak, and allows for more even development across the whole face of the sheet. This is just a personal observation. A good soak for about 4 minutes in water same temp as developer is about right.
