I'm not a big fan of a flying sperm cell either, but you can forget
that Discus or LS4 will ever become a world class. One of the major
requirement for that class is: can you produce NEW, laminate, low cost
glider that will be widely accessible to everyone that wants to fly?
NOT, can you buy a 30 year old LS3 at the similar price or if you can
buy new Discus for $70,000, making gliding even less accessible for
regular folk. Now take a wild guess dont you see any LS4, or Discus in
majority, if not all American clubs? Is it because Pewee is better? Or
is it because Pewee is cheaper to aquire and operate? If that wasn't
the requirement Poles would probably propose Jantar.
