Once you notice the potential of an "oh sh*t" moment, line break, line tangle, lines reversed, crazy gust...whatever... you need to pull the release ASAP. It is difficult to release during the event. There is a small window of opportunity to save yourself. Some people will only learn from mistakes and have be reminded the hard way...hopefully they will survive when it happens and don't make the same mistake twice.
There is something good to be said about the launch/land unhooked method. it does make sense. If you are not unhooked during a launch, you should be ready & thinking about the release. be ready. keep the kite low & to the side of the window and get out on the water quickly.
I wonder why some release pins pull down (ss/dwn), and others pull up (cabrinah/up). Too bad there isn't a standard set direction so they all pull the same way.
