I got the Double Tails Hair to work more or less by loading the base on to g8 and then clearing all selections and loading the long tails , you can move them around from there, i got pretty much the same look as in the image.
If I could borrow your post for a sec, Have you had issues rendering her. She seems to give me an error when rendering.
In my entry to the contest, I had to swap out her skin with another in the wheelchair post. Thought it might be the file size if the textures but not sure.
