3.0 main line with 2.5 sub-lines?

The main line can be equipped with 2.5 secondary lines.

3.0 The main line can be equipped with 2.5 sub-lines. The main line and the auxiliary line are two important parts of the fishing line group, which are responsible for bearing different tensile forces.

The main line is the line connecting the fishing rod and the splay ring, which mainly bears the pulling force of the whole fishing group, so we should choose a thicker line, while the auxiliary line is the line connecting the splay ring and the hook, which mainly bears the force of the caught object, so we should choose a thinner line. According to this principle, it is ok to match the 3.0 main line with the 2.5 sub-line.
