From my experience the fish will be spooked by a twitch(180) or any other movement besides your steady retrieve. Go back to the spot! 30 minutes, they next day, whatever. Approach the spot with stealth. Make the first cast(next time around) with the exact same swiimmer tied on that got the initial follow. If you do not get the same reaction then it's just swimbait fishing. Be Ready when you get the bite. Don't give up. Remember your approach to the fish that got the initial bite.
