Oldie but goodie... Used to be the favorite back a few years ago, when shackles and other spinning options were needed.

Still applicable today, the spinning spreader bar gives the rider the de-tangling ability on the fly, so the front lines of the kite don't get tangled.

It works will all harness brands and models. A good option if you are into learning loops and spins but your kite doesn't de-tangle the front lines.
