We have already established that as a whole, the paintball community is seriously under-educated when it comes to handling High pressure air systems.
But one thing that you can't rule out is that as the sport grows and we continually gain more participants the frequency of this happening is going to increase unless measures are put in place (EDUCATION) to stop it from happening. Im not ruling out the stako bottles in terms of liability, but maybe they just happen to be the most commonly used bottles in Europe so chances are if its going to happen its more likely to happen with one of them.
Weird comparison, but as a motorbike rider I am something like 75% more likely to be knocked off my CBR 600 by a Ford Focus than any other car!!
Just the law of averages.
Apparently Pball is now the 4th largest extreme sport in the USA let alone the rest of the players in the world, we have now over taken snowboarding in terms of regular participants and you consider what lessons you have to take before your let loose on a mountain!! and thats just to protect yourself.
