Paul from the bayarekiteboarding.com forum posted a great report on a 5th line nightmare we could all learn from. Basically, the moral of the story is to payclose attention to how wound your 5th line is around your center lines and always try to balance your spins to each side. Check your 5th line every once in a while by pulling on it and making sure it still has free play.
