For low ISO I use the following two settings. The first one for apertures at f/11 and larger apertures. The second for f/16 and smaller apertures in the rare event I use lower ones.
This is my default settings on import for all cameras: Canon 1Ds mkIII, 5D mkIII, Nikon D800E and D810. I used a Phase One IQ160 for a while and I used this as a default as well on that camera. For an individual picture I find that I can go higher in some cases, but I rarely find it worth while.
