Thing is
though, as far as I know, none have crashed or been repaired to
evaluate for their crashworthiness or repairability VS. other models.

Not true. Janusz Centka crashed one in Finland and he walked away from
it without a scratch, he was just bruised up.

The control surface play is certainly an issue. Someone should ask the
factory about that. Is it correctable or not? Was it down to BB or is
it fleet wide?

D-2 was tested quite extensively in Poland by Aviation Institute and
found no problem with that.

In your discussions you forgetting that all gliders manufactured in
Europe are made to EASA standard, not just the German gliders. The
same regulations are applicable to D-2 as well as to V-2 or ASG-29.
