The Libelle is a true "classic" glider.

The only negative I was told is a weak boom subseptible to damage during off field landings if the glider drags a wingtip and gets sideways. Had that happen to one at our field.

Any truth to that?

Yep
It is not as rugged as modern gliders.
JRS described above is the glider you reference
Not a reason to avoid the Libelle.
