I use Neg film as well as chrome, mainly for the latitude I get. Have to disagree with the statement made many times re chrome film handling "subtle" color, in my experience this is not always, if at all, the case.

I find that though the colours can be somewhat softer that can work to advantage in contrasty light. Also ND grads sometimes are not possible to use, neg film really comes into its own then.

Suck it and see would be the best way forward. I use Pro160s personally.
I reckon I can get 8-9 stops of latitude out of it.
