Google "45 foot gkpi skywriter tails"
I use them on both my dual line and Revs. IMHO they are fantastic tails. Look very smooth and follows the trajectory of the kites pretty well.
For Revs I just tie them on both wingtips at the bottom, ala John's pictures.
Get some matching colours with your kites and they look really awesome with the right combination
