Many gliders are not approved for deliberate spinning. Do you guys recommend spinning them anyway? My approach to spin avoidance is to monitor the airspeed, and to teach that if the nose ever goes down uncommanded to push the stick forwards.

Is it about their age or design? I'm curious if there are any modern gliders (not motorgliders) not approved for spinning by design - which ones? Thanks.
