I dont have a whole lot of experience casting jigs and spinnerbaits, etc. I have only one jig mould that i like, but i found that the recommended hook style and size didnt always work with my preferences.
That being said, it is a Do-It walleye head mould, with Eagle Claw hooks recommended. I prefer to upsize by two sizes and i sometimes cant get Eagle Claw hooks. I took a Dremel tool with a small burr on it and enlarged the space for the hook eye. That allows me to use other hooks as needed. I dont remember having to enlarge for the hook bend/point.
