I had the chance to ride the new kitebar-system yesterday.
I don't have to tell you how much I loved it, since I was save all the time while I could do my rotations and didn't have to manually rotate twists out of the depower lines.
First I felt uncomfortable with the littel balls at the end of the bar, but then I noticed that I even have better grip and more control with it. Since your fingers go around the bar and the lower part of your hand can push the balls. Hard to explain though. Once you have it in your hand you will know what I mean.
The system is easily and quickly installed on your harness.
2 QR make you feel comfortable whatever situation may come up.
The kiteproshop will post an info here, when their site is up with all the information you want including pics.
Here the first picture:
