FYI, quote from the BGA "SUPPLEMENT TO BGA ‘SAFE WINCH LAUNCHING’ LEAFLET" notes
for instructors:

"If the wing drops on the ground the glider may rotate about the wing tip and
cartwheel. If the wing drops in every hundredth launch, there will be one wing
drop accident in 800 wing drop incidents. This is a recipe for complacency and
indeed it is experienced pilots who have the majority of wing drop accidents.
After the wing has dropped the cartwheel can be so rapid that no recovery by
releasing or other means is possible. This hazard must be anticipated and
pre-empted by conducting the launch with the left hand on the release, and
releasing immediately if it is not possible to keep the wings level.

Depends on your definition of 'on'. I have my fingers
'on' the release at the start of a winch lauch. By
that I mean that I rest two straight fingers on the
top of the release knob, either side of the cable.
What I don't do is curl my fingers round it unless
I need to pull it.
