True, I almost exclusively fish soft plastics because I’m generally fishing back waters not open water. You’d be surprised how much water a decent sized soft plastic can displace. Doesn’t have to be a creature, a nice big worm with a paddle tale can thump around pretty good, make sure they’re scented. I like Mann’s jelly worm, either 8 or 10 inch, I usually go purple or black with those. A jig head will keep it banging around near the bottom, kicking up some debris. Don’t know what kind of setup your running rod/reel wise, I use medium spinning gear and will pair a big soft plastic with a 5/16 jig head, usually weedless. I like to fish weightless honestly, but my water sounds a bit clearer than yours.
