Hi Brian (and All),
I don't know if you ever saw the picture that used to be on our website but I put two of the MBHO active cable clips with capsules in one Shure shock mount like you are using. This way, you actually have a compact, shock mounted bar that holds both capsules and can be adjusted into numerous positions (ortf, etc...).
You may find the Schoeps A20(s) is more secure (especially for two mics) though the Shure works quite well.
I tried using the DPA CXO4000 but the spaces are too small to hold the MBHO's with bending the metal. Then, it looks a bit beat up.
Happy Recording Everybody,
Marc
