The all new 6th Sense Whale 4.5 Swimbait is the largest of our soft swimbait series that delivers a beefier profile, keel-style belly, and added fins. The pectoral fin feature was designed to give the Whale outstanding balance and stability, with a real bait fish shimmy action. For those targeting bigger bites with a keel weighted hook over grass or simply looking for a bulky swimjig trailer, this is our preferred size/style swimbait.
