when kite loops certain number of times, all the lines are twisted together under such a tension that safety line is not able to slide away to depower the kite. the more powered kite, more tension on the lines - less loops needed to cause this. the more powered kite, the more violent loops causing more tension on the lines
so if you do not release after first or second loop, does not matter what brand of bar/kite, if 4 or 5 lines, if safety line runs through the bar our outside, the safety is likely not to work, and the risk increases with every additional loop
also if you lose tension in lines during kite crash, or fall during the jump, or even during starting of the kite, if center line/safety line wrap around the bar - then chicken loop quick release safety will be compromised, and if they because of wrap around pull on one of the steering lines, loops may occur, does not matter what brand of bar/kite, if 4 or 5 lines
if you fly north on 5 lines, it is also important to have the 5th line correctly trimmed, so it is not hanging too loose under the Y.
being overpowered, and flying kite fully depowered on the trim strap may cause it become even longer, which can increase risk of tangles
safety line running outside bar also can cause tangles and kitemares, even more likely
just a few rotations in the same way during jumps or few loops can cause this system to totally entangle leash around bar and depower line and possibly also around the steerning lines... good luck then!
so don't rush to burn the 5th line and North like a witch while shouting it to the whole world...
that you went out after this without leash again suggest that you probably don't really care about safety, or do you believe 5th line should work its magic even without the leash?
you could have possibly killed or injured someone, should you loose kite again, in 25kts to be tangled in lines of kite flying away alone can be fatal...
would you then also defend yourself that you are experienced kiter, and it is North's fault and that with other brand this could not happen because statistics of your sessions and accidents very logically prove that?
but sincere credits to you that you draw attention of other kiters that this can happen, and that they should not hesitate to release early, so thanks for sharing the experience
it is often overestimating one's own skills, or false belief that this brand or that system is 'magic' in any situation, going hand in hand with lack of real understanding how things work that cause unnecessary accidents
