I had wind noise on the first few outdoor recordings made m/s with mk4/mk8 in low to moderate wind (nothing I would have been concerned about if running mk4's with DPA or Shure foamies. I added a fur to the WMS and that solved the problem and never ran it outdoors without the fur over the WMS ever again. I no longer have the mk8 or WMS, but I might have that fur buried in the closet somewhere.
