Photos below of the Naiant X-8S as side microphone in a Mid/Side pair, using a DPA 4098H supercardioid as mid microphone.
In use, the integral goose-neck of the miniature DPA 4098 allows it to be easily positioned in an extremely coincident arrangement atop the X-8S. I simply gaff taped both to a fore/aft oriented mic bar and slipped a big Shure windscreen over the pair for outdoor use. I'll post more details on the multi-channel surround recording arrangement this pair was a part of in the Oddball Microphone Techniques thread, here-

Following photos show the mics as setup in the array. The array used two of these M/S arrangements, one facing forward, the other facing rearward. (Note- the small drill dimple marking the left capsule side of the X-8S is not always easily visible, so I added the narrow gaff tape band to quickly identify correct polarity orientation of the figure 8 by sight or feel. Tape band = positive polarity, left side)
