OK, I don't know anything about Surfit, so maybe I shouldn't argue. But
I'll tease it for fun :). Please, tell me how you think it is possible
to reproduce the effect of the fault line in the center of the image at:


by "masking areas between fault lines, interpolating them seperatly and
patching together".

This fault line there makes the surface discontinuos only on that
limited distance where it's present, accross a single, consistent area.
I can't imagine how I would achieve the same interpolating separate
areas and merging them afterwards.

Also mind the shorter fault line here:

What do you think now?
