My 20 never turns into a 1-26, at least while I am looking. It might
be a Schrondinger's Cat kind of dilemma, though.

Other than for wingloading to go out and race other folks who only
want to fly for 3 hrs in a day, why would you need any other 15m
ship?

The 20 is my vote for the best all-around sailplane ever built. And
the 12 was a kiddie car..... until you have to land it. Then you
better be awake and on your game. I would like to get mine back.
