It depends on how fast you are going. At 200 Kt,you may get about 2" or
so of ram air pressure, which translate to about 1 PSI.

I would probably need it most at best glide speed - you know, when
there's that eerie silence up front.

Say 80 mph or so.

The ram air pressure at 80 mph would be worth about 1/4 inch of HG, or
about 1/8 psi. It doesn't seem worth the trouble to me.
