It was the bladder I think and not the strut..........and it was a new kite, you should never pump a new kite up to the max straight away, bladder bursts are relatively common on new kites as the bladders aren't always fitted correctly and haven't had the chance to get seated properly, they usually explode into the voids
So probably not the pressure, more so just a new kite and you need to be gentle when pumping up a new kite.
Exactly the same when refitting a bladder, always pump up slowly and shake/caress it so it fits properly.
My 2007 GK Sonic did the same when I first got it
rode it without end strut inflated still awesome kite
