Your setup might function.
But I´m afraid the red stopper ball will not be strong enough to carry all the load of one front line vs. the metal ring.
Be reminded that this cheap plastic ball - in the 5th Element setup - only has to carry the load of the "loaded 5th line", which is very significantly lower than the full frontline load.
If the ball would crack under load, the relatively small knot (covered by the ball) would slide through the metal ring, wouldn´t it?
In that case you wouldn´t be able to return to the beach (continously flagged out kite). And if it would happen during a high jump you would fall out of the sky like a piece of lead.
It would be better to use a smaller diameter ring and a "proper" (= lasting and not line killing) thick knot instead of a small knot plus ball.
BUT: This knot mustn´t slide through the bar hole with any resistance, or alternatively with total resistance. The bar could get stuck at / behind this knot after releasing the kite, which might make it impossible to pull the bar back to you after a safety release.
My only concerns are the ring not being able to hold the load of the front line. The ball is the same type used in the Ozone bars and they seem to hold for them, as westozzy said before.
If the ball breaks, the tension would be on the safety line, and it may be a little unstable to fly, but It would still work. If the ring breaks, is when things may get a bit uglier to get back to the beach. The Ozone part looks a lot stronger than the little metal ring (maybe using 2 rings together?). I wonder what the system for the new 2015 North quad bar looks like.
After all this back and forth, as I said in the other thread, I might consider converting the quad bar into a 5 lines using the same safety setup used in the 5 lines bar. I'd be getting an extra line for the center leaving it without tension, so it doesn't affect the arc of the Dice and still maintain the low Y from the Quad bar. 4 lines with 2 front lines safety is still very dangerous. My mate had to release his Dice on 35+ knots on the beach and he almost ended up in the bushes because of the power that he still had on his 6m kite using the 2 front lines safety. I had a similar situation once. Not very good feeling.
