The Spindle Worm is in my opinion one of the best paddle tail soft lures ever made. It simply catches fish. Used with a jighead of anywhere from 5g to 30g you can use this lure for casting or in the vertical.
The VIOS material that makes these lures so soft means they dont like being mixed up with normal latex and rubber soft lures, keep these in the original packets.
You will see that as soon as the lure enters the water the paddle tail starts working, these lures are so soft they seem alive.
