If that's the case - that I"m trying to make the refine edge (specifically the Refine Radius Tool) operate outside it's capability, I'm going to have to go find some better information on the tool... Anyhow, here's the image...

My purpose on this image is to test the Quick Select/Refine Edge since I was told it's the best way to get an optimal selection...
Take the Quick Select tool and, using a smallish size (in this case, I used 9 pixels) and select both swans. Clean up by removing excess selections and get a fairly good selection. When I did this, I found that regardless of my brush size, I couldn't get all the edges right.
Hit "Refine Edge" and used the "Refine Radius Tool" to get the edges of my selection right. It worked fine in SOME areas, but in other areas it actually made the edges worse. For example, at the bottom of the swans, where there's water showing between them, using the refine radius tool made the edge worse.
So, despite the claims that this is the optimal way to get a selection, it appears that I still have to refine the edge then take something like the polygonal lasso or whatever, and finish the edge with yet another tool...
