It is suggested that 26g fish dart be equipped with four strands 1745 rubber band. In addition, personally, it is best to use four strands of 1745. Each 8mm steel ball is 2.09g, and the 440 material 140mm long stainless steel bullet "Flying Shark" darts has more than 20g. Coupled with the cooperation of the dart tail, the fish dart will have a big parabola.
