Yes, my traditional fishing line set has one line at the bottom, no sub-bus lines.
The top is the space bean and the floating seat, then two lead pendants are placed on it, and the fishhook is tied directly below. The neater the line group and the fewer things on it, the higher the sensitivity. Of course, there is a risk that the line will drift away after cutting off the line, but if you are fishing for crucian carp, there should be nothing to worry about.
