I ran the .obj file through STOMP and reduced the render time of that same image above to 10 minutes. I forgot to indicate that I had turned off "Cast Shadow" for the hair. Something I usually do for hair that is neck length or more because I hate the black voids that often appear in the neck area with the shadows on. So I definitly advise running the file through STOMP as it will cut down on the time to render.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
