When casting large swimbaits, the type of rod action you choose is crucial for both effective casting and ensuring a solid hookup with the fish. Based on the video context provided, for large swimbaits, especially those that are heavy, you'll want a rod that has enough backbone to handle the weight of the bait and the potential fight of a big bass. This typically means looking for a rod with a moderate to fast action, which refers to how quickly the rod returns to its neutral position after being bent.
A moderate action rod will bend more towards the middle of the rod, which allows for a bit more delay when setting the hook, giving the bass a chance to fully take the swimbait in its mouth. This action also helps in casting, as it provides a good load on the rod, which can help in launching heavy baits a good distance. However, if you're using swimbaits with single jig hooks, like a Huddleston or a Magdraft with a beast hook, you might prefer a fast action rod with a lot of backbone (extra heavy power) to ensure you can set the hook firmly and handle the weight of the bait.
For swimbaits with treble hooks, like glide baits or wake baits, a more parabolic rod is often recommended. Parabolic rods bend more evenly throughout the length of the rod, which helps to keep the treble hooks pinned in the fish's mouth without tearing out, especially during the fight when the fish is thrashing and changing directions.
In summary, for large soft swimbaits with single hooks, go for a stiffer, fast action rod to drive the hook home. For hard swimbaits with treble hooks, consider a more parabolic rod to ensure the hooks stay pinned. Always match the power of the rod to the weight of the swimbaits you're casting to ensure the best performance.
