Yes, I'm also interested to hear real world experience of fumed oak. From your description it sounds a bit like Pau Ferro (which I love).Have you considered the fumed oak option?
The fingerboards on Sandbergs are quite thick and, in my experience, have a appreciable influence on tone. The fumed oak is apparently somewhere between rosewood and maple and looks great (at least, in my opinion).
I've not owned or tried an ebony f/b Sandberg though.
