I've worked out a few different scenarios, but keeping it down to eight just doesn't fit. The coast is just too fiddly and lumpy.

I've been using onionskin to trace out angles and things so they could layer over the map in different combinations. I can send along a map and the ones I've drawn out so far to Doughty with pig if you'd like, but they're all just guesses.

And I'm not sure if I got the angle right exactly with what you and Tonks and Mr Black described, so there's that too.
