I made a set of line groups in the open water fishing, and the effect was good. You can try. The configuration is as follows: the main line uses the Taiwan Province fishing line group, with a small amount of lead on the lead base, and the sliding lead group (that is, the fishing line with sliding lead above 30 cm) is added below the eight-character ring, and at the same time, the auxiliary line is tied to the eight-character ring, and both single and double hooks can be used (the auxiliary line is preferably shorter than the sliding lead line by 65433).
If there are aquatic plants, put small particles of lead on the secondary line and fish with a single hook.
Choose no. 1-4 is a float, and try to choose a slender body, small water resistance and heavy feet, which is convenient for vertical float, and the material doesn't matter. It is best to adjust the float to more than 5 meshes. Fish eat bait by pulling and floating, and it is difficult to observe without mesh.
The fish in the running water eat the bait fiercely, and the action of the fish drift is large, which is easy to observe.
