Freshwater fishing, how to match Luya fishing line best?

PE main line (if you can accompany Taiwan Province for fishing at first-if you are not afraid of the big fish running away), generally 50 meters with fresh water is enough, and then tie a GT knot, and add a pin (that is, the one with a splayed ring) with the auxiliary line (carbon line) to facilitate the replacement of Luya. If it is silver carp, it is recommended to use sequins. If it is snakehead fishing, thunder frog is the first choice. As for the specific size of Luya, just go to the fishing gear shop for consultation. Note that the reel must choose a better running line, otherwise it won't go far. Besides, don't add anything like lead pendant, it's useless.
