All good points. Variability of the situation ( ability , conditions , weight , the ability of the gear to give you a break when in trouble etc ) just cannot be fully taken into account.
Coming from windsurfing , I have always said that there is some really dodgy elements to kiting. In the plain light of day , don't underestimate it's inherent dangers.
In windsurfing , apart from getting caught up in the harness lines or getting hit on the head you can just ditch it when in trouble.
With kiting , the problem can just keep getting worse to critical from a simple mistake. We laugh it off in our stories but it's serious stuff.
On safety systems -snow ski bindings are made to release when under a certain amount of pressure. The pressure is adjustable according to your size and your ability. Hard to do with this sport I reckon ?
The greater your ability the tighter you make them as you put them under more pressure therefore the less chance of releasing when it hits the fan.
I have noticed that some experienced riders choose to go suicide even if they are not doing tricks as the brand really doesn't provide for the best safety release device. Don't think that's good enough in my book in light of the recent events.
So given the limitations safety systems currently allow. it comes back to thought processes to give the best safety possible.
The process we take should be much like flying a plane -preflight checks of conditions , location , safe launch and land ,idiots on the beach and water etc. We know flying a plane can go wrong but at least we can minimise problems.
Sounds boring and too logical I know , but there it is
Then get out and have a blast.
