I do have to apologize but your heading sent my brain into overload cause all I could think of was "star trekking across the universe" the second I seen your post.
Here. It is a piece of pipe from an old solar heating system - sort of flexible pvc with aluminium so you can bend it - but i think a straight pipe would work as well. It is about a metre long and attached to the harness with cable ties to where ever. The big bolt prevents the pipe from rotating and is necessary. The mystic harness that i have has this plastic frame on the back and I drilled a couple of holes for cable ties. The camera attaches to the pole with the handlebar or the roll bar mount. It took a bit of adjusting and getting used to, but now i dont even notice it. I think it gives a nice POV video.
