I bought a DVW 970 and the Sony rep[who is also an ex-cameraman] Showed me some nice adjustments.
The user matrix can be increased around +10 to +15 for more saturated pictures. It is important with the 970 [as opposed to a 700] that each value be the same down the line.
Another cool one is knee point saturation, turn it on and wind it up to +99. It puts the chroma back where you would have lost it through overexposure, for example, on a shiny bald head!
Give those a try, I'd be interested in hearing other opinions...
