That set of pigtails moves the towpoint up and out and lowers the stress on the frame and bridle OR it moves the towpoint down and in and increases the stress on the frame and bridle.
Out/Up: Better low wind performance, less trickability, larger hand motions required for turns and trick initiaition, larger/slower turn and spin radius
In/Down: Basically the reverse of the other.
These are general guidelines. YMMV.
