Look closely. The single line that takes the load of the two front lines is much thicker than the front lines.
Exactly, Takoon has also done this for years now, and this single front line is way stronger than the other "single" lines
In fact I would rather have a single front line break, than only ONE of the frontlines
If the single front line breaks, the kite just drops down on the rear lines, quite easy and gentle (have tried getting both frontlines cut, and seen many others where their depower line snapped).
Whereas if one frontline breaks only, when there are two, it will result in a violent fully powered death loop
So I think the advantages are bigger than any disadvantages ?
Actually - ARE there any disadvantages with a stronger single front line ? I dont know...
