If the prism tape works at a fairly wide range of angles then maybe it
can be put only on the bottom of the leading edge -- that is, below
the point at which the leading edge is vertical at a reasonable angle
of attack.

It may well still be quite visible in a head-on situation, and will be
perfectly visible on a circling glider to anyone outside the circle.

I assume that anyone inside the circle can already see the glider
ok :-)

I remember several years ago seeing photos of a soaring contest in
Europe where every sailplane had reflective tape about 10-12 inches
wide wrapped on the leading edges of each wing and the vertical stab.
Does anyone have any information about that? How effective? If it
was adopted?
