One situation is that you are not familiar with the situation and need to change various types of bait to test. At this time, it is suggested to use the eight-character ring instead of the fake bait, which is quick and convenient.
In the second case, when using hard bait, most of them need to add an eight-character ring. In particular, some rotating baits need a rotating splayed ring, otherwise the thread will be easily twisted and knotted.
Fishing for soft bait, try not to add the eight-character ring if possible. Adding the eight-character ring affects the swimming style, especially when the mandarin fish is in the way. It is normal to hang bait, and most of the bait is lost when hanging bait. If you add the eight-character ring, even the eight-character ring is gone.
The use of the eight-character ring has little to do with the presence or absence of the front conductor.
