Yes. Figure proper tension at about 1/3 to 1/2 between zero and completely stretched. Should be approximately the same amount for all six points around the sail. Of course, the ones opposite each other naturally equalize. You just need to keep the bungee lengths on the left about equal to those on the right to keep the sail centered on the frame. If you have more sail on one side of the frame, that side of the kite will want to move faster than the other.
I think the Djinn will be available in about 3 weeks and probably in all versions, but I'll let JB definitively clue us in on that.
