My basic understanding is that the 38mm ball was quick and spinny, due to this fact it was more durable to have constant rallies. Strategic gamers like Waldner, Liu Guoliang, Kong Linghui excelled underneath this ball.
The 40mm ball made the sport a lot slower, and favored highly effective attacking gamers. Wang Liqin and Zhang Jike excelled on this period.
The plastic ball decreased the spin tremendously and allowed for extra creativity, extra flicks, extra versatility in assault. Ma Lengthy and FZD excelled throughout this period.
Do you agree or am I misunderstanding one thing?
