The sound made of wood is good, but its strength is poor and it is easy to be damaged. The service life of plastics is about 3 times that of bamboo and wood structures. So I think if I am a beginner, I'd better buy plastic. I'm playing diabolo. It's made of plastic. It works well. Moreover, plastic diabolo is not pure plastic, but generally plastic steel and plastic-wood structure. It is made of modern technology and new materials, such as ABS engineering plastics, and then connected with metal shafts or wooden shafts. I don't need to buy vibrators and wires separately. I just want to buy a whole set. In addition, beginners had better not buy the one with short shaft, which is more difficult to play. The average diabolo used for fitness is about 10 cm to 13 cm.
