Watched a video on YouTube a couple years ago with Whitey Outlaw on Santee Cooper Sportsman show. He was showing how he liked to tie a tight knot so he can adjust his jig horizontally as opposed to it just dangling vertically. I tried this method last spring with decent success. Before that I always just tied an improved clinch knot and let it hang vertically. I will experiment with a loop knot this year when vertical jigging as well.
