It is a great film (as are most films that are left).
I shoot it at EI 160 and use an incident meter. I will overexpose it manually in a high-contrast composition, but I never re rate it.
What constitutes a "high-contrast composition", in which I will overexpose, is determined by first getting to know how much contrast the film is capable of grabbing.
So, the key to good exposures at box speed, as with all films, is having an eye for contrast (and/or a spot meter to check where tones fall in relation to the middle grey placement recommended by your incident meter), and making adjustments in exposure as necessary.
Make sure you try the 400s as well. There is an NC and VC, unlike Fuji. If they go away, our palette available from 400 films is seriously reduced.
