You make a great point Smudger.
It's hard for me to find a film that I don't like.
Metered at box with an incident meter and processed per the instructions they all seem to work well too. I do view as important knowing what situations I like the results of each film in.
Where I see using one film and highly tested processes as an advantage is in repeatability. That's great for commerce or setting up an assembly line darkroom process or even teaching because the results are measurable.
I'm not so sure that absolute repeatability is an important artistic quality or that that ridgid, one film, style of working is the best. In fact I find it stifling artistically.
I agree somewhat with what yos say Mark. However, knowing how a specific film and developer combo works also allows a person to bend the outcome easier, alowing for greater freedom to play. I believe that is what makes getting to know your film important.
