The shock mounts do, but with the vert bar now a horizontal bar, wouldn't the mics need to be in the same plane that the vert bar is in? I'm guessing this would limit you to DIN/NOS because the bar would be in the middle of your mics, correct?
() <-- mic stand
\\||// <-- right mic

| |___clamp/bar
|___left mic
i.e. there's no way to make a vertical bar
vertical so you can have the mics cross in the front?
Now that I think about it, if I'm clamping to a rail, I can just have the end stick up so I can mount right to it, but clamping to something vertical is still confusing me.
