The hardness of the Rose sponge is higher than that of 102, the speed is faster and the bottom strength is better, it can provide good support when exerting force, and it is slightly inferior to 102 in control and stability. The Rose's particles are slightly thinner than 102, so it is not as good as 102 in arc control, but because the sponge degree is improved, the speed and power of the ball are increased, the ball hit is more cunning and more threatening, and the corresponding requirements for ball control are higher. In general, 102 is more typical in control, and Rose is more threatening in hitting quality. Rose is better than 1002 in speed and power, and inferior to 102 in ball control. It is for reference only.
