Mostly twitching, but I will swim a paddle tail bait. Years back when I was doing saltwater fishing I used to follow a Long Island native, John Skinner, who is a very accomplished fluke (summer flounder) fisherman, though more renowned for striped bass. He likes to target fluke with a bucktail jig plus gulp. On his YouTube channel he took several underwater videos of fishing a bucktail with rapidly twitching vs letting it glide while drifting from the boat. The former was more successful in enticing the fish to bite. Perhaps the twitching motion triggers predatory fish.
