I think that all modern gliders will be going pretty fast in the recovery
from a spin. How fast depends on the skill of the pilot, after all while a
well executed spin demo in a Ka13 can be done without exceeding 80 kts a
pupil can easily go through 100 kts and be close to VNE.

I think all gliders have to demonstrate recovery from a spin but what a
test pilot can do may be beyond the average pilot. Some manufacturers may
be more cautious than others.
