I normally use either tram or cos11 with my lectro radios, but there has been a few occasions that although the cable is cream or withe, the shirt or blouse of the actors is very see-through and you can see the cable. Or the material is too tight and it creates a vein like effect.
I have 2 Countryman B6 that normally are very good in this cases, as the cable is hair thin; but i find the sound a bit thin and very sensitive to clothing noise.
What other options are around with such a thin cable? the actual size of the mic is also good, but now as critical.
