If that water was anything but muddy, use a mono or fluorocarbon leader. I'm a fan of long leaders, 24" upto as much as 48", to get the bait away from braid or terminal tackle. Offshore in the Gulf of Mexico, leaders 5'-8' are common when fishing Snapper, to get the bait away from the sinker and/or swivel.
Unless You're fishing in cover (grass, wood), fish see that braid going to that bait and know it's not natural so they're much more likely to turn away. Of course, You have to factor-in everything...was it a short time passed those fish's feeding so they weren't hungry? What was the moon doing the night before? Did they feed the night before, plus You were fishing the morning after a bright/near-full/full moon? Clear water? Did a front just hit? 1st and foremost, use a mono/fluoro leader, IMO, 24"-36" long.
