Run the top down with a wind blocker? A question for you..
 

I have a question for anyone who has a wind blocking device, doesn't matter what model of convertible, or the type and model of wind blocking device.

In regard to the piece that sits more or less parallel to the seats behind the headrests ( mesh, Poly carbonate, acrylic )....do you run yours angled back "/",
angled forward, or no angle at all "I" ?
And, if you made angle adjustments, did you find that the different positions offered different performance..or, did it not really seem to matter much?

Thank you in advance! Any and all insight is sincerely appreciated
