The king sling knot is an easy knot to tie and offers a decent amount of strength. However, its real benefit is that it allows crank baits to work freely and look a whole lot more lifelike.
In my tests I found that while working the lure it looked a lot more natural and the action was quite enticing to the fish. The strike to hook up rate was good and I was quite impressed with the knot.
