Traditional poles are soft and hard.

According to domestic standards, the hardness from low to high is soft-hard-ultra-hard. The corresponding standard in Japan is dry tone-basic tone-first tone (X tone is generally used to describe the hardness of crucian carp poles). Personally, I am used to fishing big crucian carp slowly in the management pond with a soft tuning rod (dry tuning). At this time, they pursue a better feel and fun to play with fish. In the polyculture pond (or reservoir) where the fishing speed is not very fast but the fishing force is large, the hard adjusting rod in the polyculture pond or reservoir can better protect the fishing group and avoid tangency or even broken rod. When fishing for small crucian carp, I like to use an ultra-hard adjusting rod, which can fly fish, and the rod will not shake so violently when flying fish. The above are the differences and scope of application of several fishing rods with different tonality. Of course, personal habits are different and are for reference only.
