The concept is to deal with the growing lure year by year. For example, the turtle bait is a sword over 20cm and a mullet near 50cm. Inevitably, the lure size becomes huge and the weight approaches 24 oz (about 700 g). Throwing it with a stiff rod is only a penance. However, this rod flies a huge super-heavyweight lure far away with its repulsive force. There will be more opportunities to meet domestic and foreign monster fish.
