What number is suitable for nine series slingshot shooting fish?

Because the initial velocity of the slingshot is 70-80 meters per second, the line wears away quickly, so the ordinary fishing line can't be used, which can easily lead to the disconnection and the throwing of the fish dart. Slingshot shooting fish wheel is the most suitable.

However, if the line is too thick, it will also affect hunting, and there is a certain risk of hurting yourself, so slingshots that are too thick and thin are not suitable for shooting fish wheels.
