I'm Kingpiin from Kitefreeks, and I have the NPW9 LK250. It's most addictive kite for Boarding and buggying. It holds power all over the window, and I prefer it to ANY, firebee. Upwind performace is excellent and is very smooth too. U need to add a little more brake to the NPW9 tho because its not celled and needs the sail fully opened. It was the easiest kite to set up too, and is very forgiving. It flies similarly to a Delta kite, but with the speed and pull of a Blade. Only in higer winds will the NPW9 be put away and the Firebee 4.0 comes out. Reviews done and should be posted soon at
