With a little help of Joël Durier (Phylloxera) I've finally managed to create some decent looking stratas using the strata and outcrops shader.
Joël sent me a clipfile of 2 combined stratas (stratas merged via merge shader, standard settings). Thanks Joël!
The clipfile sent me in the right direction on how to add some decent, no 'staircasing', stratas to a terrain.
See in his own image as well, here:

This way the stratas have some variaton on where they appear and whether one or both stratashaders appear on the terrain.
Another nice feature, which I didn't expect to appear where the trenches/ditches. Personally I like them a lot
As you probably can see there's a flaw in the lighting. I used GI lighting (1/1) with a fill light (to lighten up the shadows) and I forgot to give it the same soft shadow settings.
It was also a bit too strong. So you can see 2 different types of shadow in the image. Tomorrow I'll render a high-res higher detail with correct shadows (hopefully).
Next thing which I might consider is to add some populations to give the image more sense of scale. I also have to improve the surfacing I think.
Please let me know what you think of it
