They work. In a wide variety of applications and species. Brookies to muskelunge. Everything in between. There’s a pattern, size, and color for anything. I keep some in every box. Particularly good for tying into novice lines. Kids. When you just have to have something biting anything to keep the attention span on-point. I’m more into trolling spoons and collect vintage suttons for salmonoids. But, if you’re gonna cast, they’re the original ‘Spinnerbait’. I like jigging ice with bucktails.
