I have been pouring for a little over a year (basic round head jigs with sickle hooks) I love pouring it's relaxing and keeps crappie on the brain through the winter...that being said I want to venture into the pony head with blades (road runners) but I don't know what sizes I need for swivels or blades or even if that's the terminology most likely buying a 1/8 Oz or 1/6 Oz mold........ any and all help would be appreciated
