I,m racekiting for 1 year now, before i did windsurfing (slalom and racing).
Looking at the kite i think there is something still missing on the racekite....
Looking at the racesails from windsurf formula and slalom you see a widesleeve for a better and faster result (like the wing of an airplane).
For example the rs slalom from neil pryde sails has a wide sleeve.

Someone already saw a kite whith this wingsleeve behind the tube??
Maybe would be the new fastest kite.......
