I have been through this journey and finally found what I needed at Lurepartsonline.com. Just type in spoon blanks in their search tool. What you are looking for they call a casting spoon. Same thing and it is the size and the weight you are looking for, 4 inch or so in 1 to 2 oz. weights. They have several to choose from and I even put glitter tape and fixed it with D2T. Also dressed some up with a treble I put Mylar on with my fly vise. Retail on that bait you see on my Avatar is close to 15 bucks. Won't be paying those prices anymore....Good luck.....
