I call them WHISTLERS because after I finish tying them I turn them towards me and blow on the head to see how it spins and if everything is trimmed right with nothing around the propeller it makes a whistling sound. I love blade baits and these are the only ones I use when water is cold. Blades are 9/16" with a 3/32 bead. Also did a few with just thread to add soft plastics.Name: IMG_5890.jpg Views: 329 Size: 111.7 KBName: IMG_5892.jpg Views: 317 Size: 86.5 KBName: IMG_5896.jpg Views: 316 Size: 113.6 KB
