If any1 has a swivelling 5th line that passes through the bar next to the centar line and normally flies just tought or slightly slack and has twists developing up the line due to rotations or passes.... or even when you rig up with no twists, it half twists 1 way above a point and half another way below; for a possible solution

I've found an easy way to stop the line wanting to twist or remembering to twist that once the kite is in the air and your in a safe place and the lines have twisted again, attempt to rotate the5th line around the center line first to get rid of the actuall twist.then if you still have the half one way half the other twists, unclip your safety from your fifth line, then twist the actual 5th line coming from the kite in what ever direction undoes the bottom half of the twist, once thats out you can then stand on the beach and spin in circles the other way to get the top ones out.
