Competitive fishing, small fish, in the race against time environment, fast sub-wire clamp is also a good method, but there are many shortcomings when tying the sub-wire, which is not suitable for fishing too big fish, otherwise the sub-wire is very easy to break.
There is also a knotting method without knotting the sub-thread, but it takes a long time to replace the sub-thread, that is, the sub-thread is folded in half, and the end without hook passes through the loop and then knotted by hook, which is suitable for the double hook knotting method. Generally, when there are many obstacles around fishing holes and fishing spots, it is suitable to use single hook fishing. The method of tying a single hook is similar to that of a figure-of-eight ring, that is, the fishing line is folded in half by one third, then the folded part passes through the ring, then the single line is wound around the hook several times to tighten it, and then the redundant line is cut off.
