This discussion is beginning to illustrate why the nodes that load with V4 high resolution maps do not look good in all lights. <Bright_Light_Illumination> Which makes the challenge to create a naive, all/any-lighting-friendly shader set quite daunting. Not that I'm not willing to try, but the challenge is huge.
And it's not like I know what I'm doing.

So, what I might do is: learn from the experts. See what they've done, and pick their nodes apart brick by brick. I see no other option. use only those bits that will look half-way decent in most lighting conditions.

I might even include some lights...
