Thanks. I like the convenience of the CS-10EMs. I've emailed Rycote to see if they have any suitable windshields.
Even in this Roland video, you can hear the wind from the passing train.

Train recording starts at 9:41
With the Shure WL183s, they'll be less prone to picking up wind noise, but I wonder where to wear them, if I get two. I suppose I could put them on the brim of a wide brim hat...
