My Pole Shoot Idea - Focusing - Blur / Sharp

So once I had decided the set idea for this pole shoot and the what i wanted the overall film to look like, i had decided about the background colour of white and the lighting, what else I wanted to look at was the focusing of the dancer.

I have placed four images from my test shoots showing the focus difference.  I think that I prefer the blurred option a lot more and think that blurring will make the video more interesting and will give the film a sense of mystery. I want it to be out of focus and blurred also to help take away the sexiness and sexual side to pole dancing and hopefully show more of a dance approach.
