The plastic gutter mesh I am aware of, and have intended to use. Which is fine and dandy for a TUBE. The issue arises with the termination of the tube. A flat plate allows a certain shall we say drum head. No matter how tight you get the material near it, it still flexes and does the drum noise thing that doesn't do a recording much good when it's not part of the performance. Continuous curvature allows a certain tension and distributed load that prevents most unwanted sounds.
Granted that we're not talking about a 55 gallon steel drum, although that might provide the best windscreen to mesh ratios. For use with any stereo configuration. Although not really a wind profile I'd desire to use in my region. And a hard sell at most venues. But still for my mics, the point of interest is that end of the tunnel. Versus the walls of the tunnel (tube). Although it is probably just a matter of scale to make that distinction.
I like the frisbee ideal mainly because moisture and wind profile are minimized. Although odd reflections are inevitable that route. Putting a single loop of fake fur with bungee like seems seem to be the way to go. Not that I intend to fly the equivalent of a basketball on the end of a flagpole. Although I will if I have to. Part of the reason for getting into the recording thing is to overcome the shortcomings of so called pro outfits that deem sporting rain capes and other weather compensation measures outside of their means. Even though "they" specialize in OUTDOOR event recording.
