As I look at information on Renegade Kites - Pam Markie's company - it seems they were based in Fremont, CA. And as I look at the details of the construction on her kites the quality and attention to detail is much higher on her kites. This nicely finished tubing center T - with the bridle lines inside the tubing - and the well done reinforcing and stitching.
So I would guess that the builder of the kite I have simply picked up the idea for the standoff style. I will drop dean a line and see if he knows.
