Are you sure the Bing image is correctly aligned? There is no guarantee that it is. Find a bunch of GPS traces nearby for a road or other very visible feature and ensure they line up with that feature on the Bing image. If they do, you're fine- use the Bing image to correct the coastline. If they don't, then use the tools in Potlatch or JOSM to move the Bing layer into alignment *then* correct the coastline. The coastline should follow the line of high tide. Use your best judgement to determine this. You're not missing something.
