I just got the 10. Was out in about 18 to 20 yesterday and all I can say is HOLY CRAP! I think this is the best kite I have ever owned! Its fast, its stable and it goes up-wind like it has a motor on it. It jumps so well its like it has rockets on it! I flew a demo once before and I knew I liked it but you really cant tell from one session. In the jumps If you pull on the bar as you come down you can feel the kite lift and extend the time in the air. The bar pressure is light and everything about the rig is well made and comfortable. I can see how extremely high jumps are possible. I had students to train so I did not get all afternoon on it. I let several other riders try it out and they all had big smiles. I watched one guy who has Naish, Cabrina and Best kites try it. His jumps went from low, slow and sort of sloppy to high, fast and controlled. I think that anyone wanting to get into the sport or wanting to take it to the next level should try out one of these. I think it will surprise you.
