that swing jigs cost the buyer so much. I've been making up some. Not only do I have the cost of the wire forms and hooks, they are more difficult to mount in the mold than a regular jig hook, they are harder to paint and keep paint off the hook eye and wire form, plus they are longer than the average jig so they take up a lot more space than a regular jig when put in the oven to cure the paint.
I'm sure glad I'm not trying to make a living making and selling them.
