there's only one knot on the bridles for your front line attachment - The Dyno for example has two knots, one for if you're riding 5 line, and one for 4 lines. I assume the reason the kite rides a little differently on 5 lines is because the split of the front lines is much higher up than on the 4 line setup. Don't ask me what this does, but it changes the direction that the front lines are pulling from. The 5th line does nothing, just hangs there loosely as a safety feature.
... yeah thats why I asked to see if Eppo had changed positions (had the Dice had two knots), but it looks like it doesn't!
