Well I've only had three sessions with my new X2 10 so far. So I don't have a lot of hours testing the kite yet. Sorry if this sounds like yet more "hype" but the god's honest truth is that on my first time out with this kite, I went upwind faster and further than I ever have before. Perhaps the conditions just happened to be perfect for my body weight, board size, etc...whatever. I've only been jumping a short while but my first time out on the X2 had me jumping WAY better than I had jumped before. Probably just me getting my technique down better. Don't want to make like it's a miracle kite or something. Then I botched a jump and the kite went down. I gave one hard yank on the center lines and the kite rolled over on its back. Ten seconds later, it was back in the sky. Maybe I just got lucky. Otherwise, I found the kite to be VERY stable and almost impossible to luft. I like the new bar allot and feel more secure because of the improved safety systems. Compared to the ARX 9.5 and the AR5's I've been riding, this kite is a Big Improvement. I'm stoked and planning to get a quiver of X2s. Of course this is just one opinion and results may vary.
BTW I don't sell or otherwise have any affiliation with Naish products. Just a happy rider, that's all.
