moon waxing said..Kitepower Australia said..Maybe people are doing things with their kites and bars that the manufacturers had no intention of designing for and none of the manufacturers are brave enough to say that yet??

Am I reading your post wrong? This is from the Cabrinha website, a harness with an attachment on the back...

Yeah, completely wrong, sorry. Just because there is a combined handle and loop on the back of the harness does not mean you and anyone should be putting their leash there!
Pretty sure that harness and most that I've seen have rings on the side, and the possibility to loop some rope to the spreader bar to attach a leash to a fixed position.
Devils advocate cap on again though, because a harness has a loop across the back, does that mean the manufacturer is responsible if you choose to attach your leash there?
In a similar vein, if you choose to unhook, and then choose to try a high risk bar pass trick, and you get your leash caught somewhere, and the kite starts death looping, is it the manufacturers fault? (Keep in mind that you still have a method to release the kite, via the leash QR)???
If something goes wrong with your kite as a direct consequence of your poor technique, bad timing, a wind gust, is this the manufacturers fault (or your own)??
