Easy question, use 80 ISO.
Is it?

What is the effect of highlight correction turned on and working with a base iso of 160? Doesn't that give you more highlight, at the cost of loosing some of the lowlights and ending up with just a little bit more dynamic range?

I don't use cameras highlight correction, but I have to tell you I am a Zone System guru and teacher locally (locality is not small), I am telling this because I am trying to explain why I don't use it, not for the ego boost. Am I perfect! No!

Answer of your question is best solution is creating a HDR, that recovers from both sides, if you don't want to make a HDR, you have to decide which side you can sacrifice, then recompose and remeasure the light. For instance in the classes I give a white cat walking on the coal pile example, which one you want to emphasize? cat or the coal? You decide that first and measure that and lean just a bit to other side (dark or white). Also PP software tremendously help on this.

Ansel Adams golden rule of "shoot for the shadows and develop for the highlights" days are now over with digital shooting, I can recommend you a perfect book Bahman Farzad's) "simplified zone system", it is an excellent book for creating moody color pictures with zone system.

But OP is nothing to do with all those, in straight simple RAW shooting , you get most of the DR at lowest ISO.

Okay, but that is for shooting something in still, but when it moves there is no HDR to make
Take this one I made (it is from the DA*60-250mm testing in lenssection):
https://dl.dropbox.com/u/20195454/_K5E7884G.jpg
It is made at iso500 (so I could win some quality going to iso160 and there was enough light to do that) with highlight correction DRon. It works as a push-pull system to give you more headtroom with highlights. Question is, when this was made at iso160 (and not the iso500) would it be the best choice and not using iso 80?

I see that even flying hair of the girl is frozen. So, when DR is the physical capability of the sensor, why ISO 160 would be the best choice if you can achieve like 1/500sec with ISO 80? If you don't have such a chance you just don't.
