Orange markers on the glider. Paint or stickers?

At the refinish I want to have the orange markers back on.

This would be a good opportunity to leave the orange
markings off. Many
years back, there was a study in the UK by the Cranfield
Institute that
confirmed that the orange "anti-collision" markings so
popular actually
made the glider LESS conspicuous!


But wasn't this Cranfield study done with dumpy motor gliders?
Falke, Grob 109, which are (relatively) easy to see? Without
anti-collision markings you cannot fly at any French gliding
site. Hard to imagine that many Alpine pilots think they would
be more visible without their day-glo orange markers!
