Points:

The buoyancy of your waves is limited, so you need to allocate water according to the model. For example, 3B wave, if matched with 3B water, the buoyancy of shrimp is just right, but the state of shrimp in water is not good, but if G2 shrimp bites lead, it will be elegant to float in water.

Nominally, the buoyancy of each wave will be a little larger. As mentioned above, if you want to hang shrimp, you should put it in 2B water, which will have at least 1B+ buoyancy. Minus shrimp, you can still bite lead.

Usage of biting lead: try to stay away from the hook when there is no running water or the water is slow. If the current is fast, it will be closer to the hook and add more, because the current will wash up the hook, hook and bite lead.

Try to ensure that the distance between your hook and the eight-character ring is an arc.
