Well said Wander, Arclite, Pobjoy and others, whom I recognise from their postings as ex VGS instructors with vast experience between them.
We used to look up to the Centre instructors, many of whom came up the same way as the rest of us, by starting as weekend gliding instructors at the "schools". We had great respect for them having worked through the system, and they had great respect for us.
We need a new broom, complete with head and new handle, to bring back the fabulous gliding organisation that we all knew and loved.
