Re speed, for the world PKRA Speed championships for 2007 it was good to see an Australian owned and designed kite company get 1st place in one of 3 heats and an overall 2nd place for the PKRA Kite Speed World Cup. 1st Place WALVIS BAY 2007 OVERALL RANKING FRANCE Sylvain HOCEINI 12meter monkeykite Griffin in 36+knots http://www.kitespeedworldcup.com/2007walvis-overallranking.htm 2nd place Overall ranking FRANCE Sylvain HOCEINI 12meter monkeykite Griffin in 36+knots http://www.kitespeedworldcup.com/2007overallranking.htm From what I have read and designed, Higher aspect kites tend to go faster and jump higher, if you are after a fast kite look for a high aspect kite with a smaller Leading edge. Medium aspect kites tend to have a more consistent pull and wider turning circle.
