I don't know the OR bar, but if the front and back lines are the same length, and there is no Y-set up high up on the front lines, I cannot see why it would not work. In anycase all you got to do is mod the bar a tiny bit.
OR might have kookproof connector the opposite frontback line pair..I dunno. If my buddy on an OR kite comes down to the beach today I can take look at his bar.
The 6 park...is....magic.
