What is the best distance between the hook and the tin ball?

According to the speed of the fish and the situation of the fish mouth, the distance between the fish mouth should be reduced and the fish mouth should be increased. When the fish mouth is light, the distance should be reduced to increase the sensitivity of the line group. Generally, the distance between hooks is 2 to 5 cm, and 3 to 4 cm is the best, depending on the situation of fish. If the fish in the fish pond is large, the distance between the lead pendant and the hook can be increased.
