The heads are 1 1/2" in length and the bait weighs 1/2 of an ounce. They come with a 4/0 single weighted hook that may be replaced with a 2/0 treble if fishing open water. The blades are #5 Colorados. The post has a loop at the back end of the bait to add either extra weight or a trailer. The head rides upright and wobbles behind the rotating blade.
