The Sennheiser MKH 8060 will fit in both the Small and Medium Cyclones.
Depending on your microphone selection, depends on which Cyclone I would recommend.
If you have a range of microphones with a length between 150mm and 260mm, I would recommend the Medium Cyclone.
If you have a range of microphones of a length up to 150mm, I would recommend the Small Cyclone.
The Medium will be out summer 2015 and the Small should be out later in 2015.
