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. Inshore this shape is effective on many different species of fish including moi and papio. You can rip this bait through the water, or do a rip and pause and rip it again , 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.
