Hey, you are giving away our secrets! ;-)
If you tell them how we make skies noise-free without hazing on the top of trees and masts, I'll come over again with a few bottles of the most unsweet wine I can find :-p

No honestly, I have Ninja noise too and I never use it any more. The thing is that de-noising your photos all over is pointless and can make them plastic. Been there, done that. Not all parts of a photo have visible noise, and a robot program (edited: as well as a SS reviewer - joke) just can't distinguish between texture and noise.

The answer is selective noise reduction on darker parts and sky in a separate layer (by the CS2 noise reduction filter), then sharpen the underlying image, and flatten. You never should sharpen noise-prone areas.
The lab color sharpening only in the luminance channel is great to avoid halos.
