If you are just going to pour for your own use I would go with the JNR-6-A or the JHB-7-A. This way you will have all the sizes you may want to use. Even pouring one jig size at a time it doesn't take long to pour 25 to 50 jigs. I agree with Fatman, I would go barb-less. A little dab of super glue and the plastic jigs will hang on tight.
