I think that there are quite a few good working Quick Release Solutions and Safety Systems on the market right now. The problem is that nowadays you need systems that work well for unhooked riders and hooked-in riders.
At Spleene we took a good look at the various aspects of safety systems and came up with a double safety system.
When our first (primary) Quick Release is actiated it pulls on both front-lines of the kite until it is totally depowered and if that isn't enough you have a Total Release Option which completely disconnect the rider from the kite and also disconnects the Handlepass leash at the same time. It is possible to use this Total Release Option straight away without having to use the first release.
To me that is as save as it gets but I am sure there is always room for improvement.
Our first Quick Release uses a somewhat similar release solution to the well proven Cabrinha system which has pretty low release forces.
However, we made the red plastic release part a bit bigger and moulded it into a mushroom shape which I believe is easier to grab and protect the hand a bit more.
On top of this we enabled the top of the chickenloop to spin and unwind the flying lines when the bar is pulled towards the rider. I believe that this is an excellent system and works much better than most swivel type devices above the bar which often don't unspin the lines properly.
Here is a link to the manual of the Spleene "IQ"-Bar and release system which shows everything in detail.

with due respect if a line is caught in the hook, your system does not address this issue.

having spent two season teaching on busy beaches the line wrapped around in bar is not that unusual as scenario

just do it

You are right, in this scenario you will have to use the release which is hopefully on the handlepass leash.
What I meant is that most people ride a suicide type set-up when riding unhooked and hook there leash directly onto or above the chickenloop.
The problem with this is that if you are in trouble whilst being hooked-in and activate your chickenloop, the carabiner of your handlepass leash might not disconnect from the chickenloop and thus you are still being dragged.
On the Spleene system the HP-Leash will disconnect at the same time and you don't have to constantly change where your HP-Leash connects to during your session. You leave it in one place, whether you ride hooked-in or unhook and you know that all your safety functions will work.
On some chickenloops it also works with a very large Carabiner clipped directly onto the chickenloop but on a lot of them the carabiner of the HP-Leash can lock itself and gets stuck in the chickenloop even though the chickenloop is open.
Obviously if you are unhooked and let go of the bar then you aren't near the chickenloop to activate it. In this scenario you need another release on your HP-Leash which is always within reach.

Sorry, you lost me there!?!
Do you mean that if one of your 4 flying lines gets caught in your harness spreaderbar the Spleene system doesn't address this scenario?
If that is what you mean then I am sorry but no system does this and here I suggest you get yourself a good knife :thumb:

Yep, this is not that uncommon a scenario for inexperienced kiters.
No system does that. This is the idea of this, post, to explore idea.
Toby has a great thread going as well.
