The double-stranded method of the figure-of-eight ring is to fold one end of the fishing line in half and put it into the figure-of-eight ring, tie a knot on it, then wrap it around several times and put the other end through the folded part of the fishing line.
The tying method of single strand is to tie the fishing line directly in the figure-eight ring, then wind it up, and then tighten the rope after winding it.
There are certain standards for the collocation of the main line and the auxiliary line, and the auxiliary line cannot be thicker than the main line. Common matching criteria are 0.6 main line 0.4 sub-line, 0.8 main line 0.6 sub-line, 1.2 main line 0.8 sub-line, 1.5 main line 1.0 sub-line and 2.0 main line 1.
The size of the hook should also match the sub-line of the main line. Generally, hooks No.2 and No.3 can match lines of 0.4, 0.6 and 0.8, hooks No.4 and No.5 can match lines of 0.8, 1.0, and hooks No.6 and No.7 can match lines of 1.0, 1.5 and 2.0.
According to the variety of different fish and the change of season, the fish with high tension will use stronger thread groups. Generally, fish are more active and struggle harder in summer, and the fishing rod and line set used are stronger than those used in winter.
