Well, to turn this bar into a 5th line system, I just have to add an extension to the red line so that it reaches the kite, and untie the knot this one has were the Y begins. This way, it will flag to the 5th line instead of stay flying on the two front lines. This bar is almost the same as the GP bar. The diference is the 5th line.
You really want 10 meters of bar throw when you flag to a 5th line. The redline system doesn't throw that far I think it goes 2 meters? so it could kiteloop after quick release.
