Robert has a good point: Everyone willing to more for a sailplane than
for a house should demand the very best in accessories and options.

Wandering off-topic, the other day I was flipping through a book
called "Graphic War," which shows and describes the technical drawings
used in the technical manuals of WWII aircraft. I was probably geeking
out from the tech writer perspective, but some of the stories behind
the documentation are as interesting as the stories behind the
aircraft themselves. Okay, maybe not, but I'd argue the case.

Anyhow, one of the drawings was a cutaway of the tailwheel and swivel
of the Junkers JU52. While the text described it only in terms of its
advantages over the tailskid, the drawing showed, in addition to the
tailwheel, a tow hitch mechanism with geometry identical to that of a
scaled-up Tost E85, right down to the actuation sector and the
mirrored torsion spring that holds the release knuckle down.
