160C is my least favorite film among Kodak and Fuji's "pro" color negative offerings. There's nothing wrong with the film per se; I just don't like the look of it. While it's saturated and crisp, to my eye it has a tendency towards a green cast that I find very unpleasant. I don't think this is related to my development, because other films developed as part of the same batch look perfect. I have found this greenish look to be stable over time, under a variety of shooting conditions, so I must attribute it to something intrinsic to the film itself.
Its Kodak analog would be 160VC, which I find far more pleasing. That, and Ektar, are my mainstays for general use. For portraiture I like 160/400NC and 400H. I prefer the 160 ISO films for their slight advantages in grain and sharpness over their ISO 400 counterparts. I find FC 160S to be the most "neutral" of all the films, but lately I've found it a bit bland for my tastes so I'm putting it aside for a while after I use up my stock.
I go back and forth between VC and NC; right now I'm tilting back towards NC. Maybe I've had enough saturated color for a while! It's good to have such a vast array of color-negative film choices.
I store mine in the freezer, taking out only a day's worth at a time.
