Martin,
Dark under wing shows up better (my opinion and article I just read).
Large contest numbers or European registration numbers under side of
wing stand out well.

Well, big dark registration would certainly show up better than unlit
reflectors. That was my point: that reflectors mounted where the sun
never shines on them aren't a lot of use.

However, while large, dark registration or comp ID is readable on a
glider that is within a fairly narrow overhead cone and probably not a
lot more than 1000ft above you, its unlikely that they are even visible
if the glider is more than a kilometer away or 2-3000 ft higher.

IOW, I don't think the reg etc. make any difference to the visibility of
gliders that are over 1 km away and in any case a glider should be easy
to see at that distance if its above or below you.
