I too like to make my own spinner jigs. I have found that rather than using the pony head, a round head can be utilized in much the same way. I paint the heads then slide a crane swivel over the hook and up to the back of the head. I then tie the jig in the same manner I would tie a non spinning jig. The swivel stays put if you tie the body tightly. Add the split ring and a spinner and you have a very good looking jig at a fraction of the cost of the real thing. I'll add a picture if someone will tell me how!
