Looks very interesting! I have two more questions.
1) If you want to rotate the bar after a loop, can you let go of it or will it be out of reach then?
2) If you rotate much more to one side, the way I understand the system, the two front flying lines will intertwine below the ring, wright? And with a lot of that it will lose its primary safety feature? Is there a way to undo that besides rotating more in the other direction?
reply to 1) The bar will be out of reach if you let it go. So I just rotate it hand over hand. Or kind of spin it with one hand holding it in the center around the lines as if you were hold a baton. Or with the kite up high, you can spin it as you let go, then tug the center lines down a few inches to bring it back down. I suppose one could put a stopper on it and BRM could have easily done so.....but this is what they say on the website: " I prefer no restriction on how far I can extend the bar without hitting a stopper. I feel the massive dangers of any limit on depower travel far outweigh any convenience. When just riding back and forth this is maybe not a big issue. But situations do occur where the kite is positioned much deeper in the window where far greater bar travel is needed to achieve the desired angle of attack at the kite for performance and safety."
reply to 2) If you keep rotating via kiteloops in one direction only you will intertwine the flying lines. I tested it today. The intertwining occurs above and below the ring, spread out....more above. It did a whole bunch of one direction rotations but eventually it will compromise the single line flagging due to increased friction. (My Naish bar doesn't have a swivel and the swivels on one of my other bars doesn't work reliably so I already had a habit of looping both ways...but I guess others without the habit and who might loop a lot in a session would have to make sure to do that.)
So...you're right on both points. I do think the "primary" safety feature is actually the great depower when you just let go of the bar. The rear lines are slackened about a foot more than when I let go of the other bars. And of course I don't over loop on one direction so many times, so the flagging stays intact. If for some reason it ever didn't flag...your hand doesn't need to move, it is right there between the two quick release balls.
