Here is a Brads Wiggler on the left and a Wiggle Wart on the right, notice the Wiggler has a dimple on the bill, the first batch didn't have that. Like I already posted these new wigglers hardly ever needed to be tuned and caught alot of Silvers. I think they have a smoother action then the Warts. I don't like the hooks they come with so I switch them out with a #4 Owner treble on the belly and a barrell swivel in between.
