i've got a safety leash that comes off a wrist band and is connected to one of my kite lines, when i let go of the bar the bar shoots halfway up the line and the kite looses all power, so it works but it's a real pain to untangle the twisted lines after.. and i use the quick release a bit

I have seen other people with a system where they let go of the bar and the bar only goes a metre or so away and the kite floats down without wrapping itself up. I've never had a chance to ask someone with this setup what the difference is, it seems like my wrist band way is no where near as good.. is it simply a case of moving the stopper ball down or is it a different system?
whats the verdict? I realise that the wrist band way gets u tangled up when u twist under the kite, to fix this can i attach my leash to a loop of rope on the back of my harness? And then attatch the leash to that?
i'm riding either a 11m or 15m 05 4 line fuel
cheers
