Is it better to run lead as hard as possible?

no. According to the fishing net, the weight of running lead will affect the sensitivity of the line group. Because the eight-character ring and the lead base are just adjacent, it is necessary to judge the sensitivity of these two methods by the underwater state of the wire group. The sensitivity difference between them mainly depends on the weight of lead. The heavier the lead, the duller the line group will be, the greater the sensitivity difference between them, and the smaller the sensitivity, the more suitable for fishing big fish. Therefore, the heavier the lead, the better.
