This design was no accident, though. Neither were the six additional fins added to the bait, again setting this swimmer apart from several of the rest. The presence of two vertical fins, one above and one below, and the two sets of flared out fins underneath are what I believe makes the bait fight so hard to stay upright where other baits tend to roll over when the speed of retrieve is varied. With the Sick Fish, if you speed the bait up, it stays upright, the same as it does if you kill it.

If you do kill the bait, it will nose dive a bit depending on how you have it rigged, but it doesn’t fall over to one side and spiral. Instead it kind of torpedos through the water keeping its swimming action, simply changing course. Which looks more like a real baitfish trying to evade a predator.
