To keep big swimbaits running straight, there are a few methods you can try. One common technique is to use a bait keeper or screw lock to secure the swimbait to the hook. This helps prevent the bait from twisting or turning during retrieval, keeping it in a straight and natural position. The video by Wired2Fish mentioned a "B lock keeper" that holds the bait in place without the need for superglue. This can be a helpful feature to look for in swimbait hooks.
Another method mentioned in the videos is to rig the swimbait with a line-through setup. This involves running the line through the body of the swimbait and attaching the hook at the end. This allows the swimbait to move more freely, resulting in a more realistic and natural swimming action. The video by Bass Fishing Tips & Techniques by BassResource demonstrated a simple line-through method using an overhand knot and a toothpick to secure the line.
It's also important to properly align the swimbait on the hook. The video by BigBassDreams mentioned the need to make sure the bait sits straight so that it swims properly. This can be achieved by aligning the hook with the backbone of the bait and using super glue to secure it in place.
Overall, the key is to find a method that works best for you and the specific swimbait you're using. Experiment with different rigging techniques and observe how the swimbait performs in the water. Remember, swimbaits are designed to mimic the natural movement of baitfish, so keeping them running straight is crucial for attracting bass.
