And if you make a third generation , polyhedral outer panel and blended
winglet like Keith Ashman's A7 - you get a quite competitive 18m ship.

In strong conditions A7 has been able to pretty much match the JS1s -
and that IS saying something...
Not bad for a 20 year old design.

I don't know what could be achieved with the LS6 because I have not seen
any examples of one being modified to the same degree.

Eric, your observations leave out what (second generation) winglets do
for the 20 -- not for the least reason that the original droop tip was
a real aerodynamic dog.

Modern tweaks on the 20B render a surprisingly competitive glider in
15m. Ask UH, it goes.
