I have winners of 4.5 meters and 5.42 meters, and the pole vault work is more detailed. The wall thickness is also uniform. I have also done tests, the fishing weight is about 1 1 kg, and there are two bottles of mineral water. The pole is relatively thin, and you are not afraid of catching big crucian carp and occasionally encountering big fish. The waist is stronger and the curvature is better. The others have not been used yet.
