I just bought my first roll of it today in 120. I've shot enough of the Portra 400 for it to be my absolute favorite color negative film. If the Portra 160 is anything like the 400, i'm sure i'll like it too! My only worry is that I like to shoot my CN films at a stop slower than they're box speed is, and ISO 80 isn't really too fast so i'm not sure if i'll be using it as much as the 400, especially in the Mamiya. All my Nikkors open up to f/1.4, so ISO 80 is OK. 4th of July is coming up, and the weather is going to be real sunny, so i'll probably shoot my 160 roll then and see what happens.
