1. Material and technology: Black Golden Falcon is made of high-modulus carbon fiber and metal, which has the characteristics of light weight and high elasticity, and improves the overall performance of the racket. 100zz is made of ordinary carbon fiber. Compared with Black Golden Falcon, it lacks in material and technology, which affects the performance of the racket.

2. Torsion-resistant lifting: The middle pole of Black Golden Falcon is strengthened, and it is upgraded from 6.4 axis to 6.5 axis, which increases the torsion resistance. This makes the Black Golden Falcon feel and stability better, and can achieve more accurate attack performance. In contrast, 100zz is not as good as Black Golden Falcon in torsion resistance, but slightly inferior in ball control and stability.
