Boy, for ISO 8000 on the D700 that is incredible - job well done!
I am curious about the higher Radius of 7 in the first pass and then the Radius 93 and threshold 18 in the last pass.
I think super high Radius is useful in high ISO is that correct? I have a 15,50,10 setting that I have used in higher ISO where I have a blurred subject due to subject motion or missed focus.
Anyhow I am interested in your thoughts.
BTW, I just tried 40,7,4 followed by 17, 93, 18 on an ISO 3200 Nikon 1 V1 that was pushed a further 1/2 stop in post and that was rather noisy using conventional sharpening. I believe it is quite improved, here it is:
