The soft plastics are hot right now for flounders. Z-Man and others are designed to be used with Procure and the scent helps.....sometimes.
I prefer soft plastics over minnows this time of the year as a high % of the fish being caught in the Southport to Topsail area are undersized and jigs have less risk of deep hooking.
Anything that will get the fish to hold a bait a little longer to give you a chance to set the hook is worth the 6 bucks. Pro Cure is some good stuff, I use it all the time.
