True, before the wing "let go" there was (almost always) an absence of
aerodynamic burble felt through the stick or one's butt or merely
"drummed" through the metal fuselage, but by the time the wing did let
go, "all the other usual suspects" had put in their appearances: low
wind noise; nose noticeably high; controls (especially stick) getting
sloppy; etc. Subsequent to checking out in the ship, I found it
"intellectual fun" to mess around with it in slow flight "trying to find
the burble." Abrupt departure from controlled flight - yes, indeed! "No
warning?" - not by a long shot.

The nose was not noticeably high in either glider (20 C or 26E); the
wind noise was subdued, but both gliders were very quiet, and the change
in noise was very small; there was no burble or "butt feel"; the
controls were light but not unusually so; and the wing "departure" was
not abrupt - I simply ran out aileron, and the wing would start
downward. I'm guessing the inside wing tip doesn't stall, but can't be
sure about that.

Stick quickly a little bit forward restored aileron authority?

The normal spin recovery works fine; even quicker was moving the flap
lever forward to the first negative flap position. I don't recall if
only stick forward was enough.
