The 4-inch I'A is a unique bait that has a similar profile as many of the baitfish that are on the menu of predatory fish in both saltwater and freshwater. The larger 4-inch profile usually means larger fish caught when fished as compared to fishing smaller baits like the standard 2-inch curlytail. Offshore this shape is effective on many different species of offshore fish. You can rip this bait through the water, or a rip it through the water and pause, or retrieve it slow, or do a slow and pause, or anything in between and it will catch fish. It has a subtle twitch when it slowly sinks on a pause.
