Why doesn't one brave country step up to the plate
and organise a one off 'one design' competition. If
it works, keep it up!

ie, there'd have to be a very healthy amount of Cirrus's
in the UK, or LS1's in Germany, maybe Discus's in the
States..?

Obviously many people and their dog have winglets these
days, just hit them a 1% handicap penalty or have them
put their old wingtip stubs on for the comp..

Keen on your thoughts..
