Macro with Lightsphere II

I have been trying out the LS II with the Nikkor 105 micro.
The light is perfect for macro, soft and diffused. A potential downside is that the LS II sits a long way from the lens when the SB800 is on the camera - which I imagine could be a problem is some situations.
Here's an example
