On this one particular point, use Bing for positioning with caution in
coastal and hilly areas. The parts of Cornwall I've mapped (Polruan
being the biggest example) have shown that the Bing imagery is only
coarsely rectified. Where there are steep hills, the features on them
aren't positioned correctly.

I've found that OS StreetView matches my traces much closer in areas
like this, so use a combination of sources and some judgement.
