Your on the right track I don’t have a chart but to reach deeper waters go heavier . Same aspect if you going shallower go lighter. I’m a double jig runner so I had prefer to run doubles but some folks run a split shot up above the jig to reach deeper depths . You also can adjust depth by running shorter or longer lines or speed up/ slowdown . Just play with it the more you do it the easier it will become! Hope this helps ya
