I've often wondered during kitesurfing lessons, which lines need to attach your safety leash. Here's the discussion about the relative advantages of attaching a variety of different items available on modern dragon.
Security on the back line / Oh shit handle: Using the back row as his security lines often results in a "death spiral", during which the kite turns quickly after we withdrew its security issue, so still gives a significant amount of pull. Even when the kite hits the water can continue to try the loop, often sitting on the water, and then twitch like a dying beast, before rising up to the loop once again drags you further down the wind. It can be a truly terrifying experience to a new Kythira. Your lines may end up with lots of twists, and even if it behaves and sits on the water, the dragon can still have a significant pull. This applies to all inflatable kites, including bows, SLE, and C's. I'd use it as a last resort only, but it is nice to have, if your system fails to others.
Security on a frontline: Very simple, but in my experience, probably the least desirable of the flag-out system. The front lines as a rule, carry more tension than the back line, and if line breaks, it is more likely to be a battlefield. In this case, a 50% chance for your safety line with the proviso that it breaks, then you got problems. Also, many kites will continue to retreat when he marked on one line.
Security on both (2) front line: Many dragons will continue to be dragged into position smiley (dragon on his back), with this system because, unlike the fifth row, trusts do not allow the kite to roll over on their back in full. In the last year or two we have seen great progress in the design of trusts, to the point that a good system can depower kite completely even in the smiley position.
The fifth line which runs at one point in the center of the leading edge: The most effective way of killing instantly the power of the dragon. Your safety director must be long enough to depower be effective, usually about twice the length required for the front line (s) system. fifth line system also makes for the easiest relaunch in light wind, when the dragon on its leading edge with a dragon inside facing you. The biggest drawback of this system is that you have an additional line that takes a little longer to set up and solved.
Armed with this information, perhaps its time you took a look at your dragon and system used to depower him .. Have you ever tried it? For most people the security system is something you do not touch when they need so I have no idea how the dragon is going to behave once it was pulled security. Test your systems always have a Plan B.
