must have slipped my notice that airbrakes on 'modern
low drag gliders' were speed limiting. my speed stays
pretty much constant at full travel.

Of course, if the glider is already running at Vne I wouldn't pull the
airbrakes but try to recover really carefully. But up to ~220kmh, I'd do
this, because they DO produce a big drag an make the glider slower (in
my experience at least, which doesn't include a Nimbus or the other big
ones).
