Tuning a kite is not just about making either the steering / front lines longer or shorter. I get that. But for kites that have a mixer like Flysurfer kites, is it the same principle in tuning the bridles? My Pansh is up for sale, but I flew it out of the bag last week for the first time in a year, to see if everything is ok. Alas, the leading-edge crumbled on me when the kite went to 12 o'clock. It doesn't tend to happen along the other areas of the wind-window, such as 3, 2 and 1 o'clock, but only when it's at zenith. And not all the time, sometimes. The problem I think is that when the wind dies down a little, the leading edge collapses, and doesn't hold its shape like a Flysurfer does. The kite used to fly perfectly, and I think some bridles have either shrunk or stretched. I was told that by shortening the B or C (or both), this problem tends to go away. I've not done that yet, but when I do align the bridle connecting points, they are about 2-3cm apart in this order: A is longer, followed by B and then C.
What tips/advice could you give please?
