I too have been suffering from the occasional "spinewrap with the inhaul bridle leg"; so I've added a couple of lengths of bridle line as suggested - problem solved
OK, I went out flying last night - what a briliant, fantastic kite. I even managed to do a couple of things I've been trying (but failing) to do for ages. As the evening went on the wind got lighter and lighter but I could still trick no problem - In fact, I'm amazed at how low this kite will go.
