SDI cable ercommendation needed

Hi All,
I have equipped my BMCC2.5 rig with a SmallHD field monitor. The monitor is mounted on a magic-arm like device so I can rotate it on all axes, which is fine. However, the SDI cable I am using is rather stiff, so the degrees of freedom are very limited.
I am now in search for a more flexible, maybe thinner cable and would like to know if you do have any recommendations for me.
