Interesting observation. There is similar match which happened 2 years later - Joo vs MaLong. We know how powerful MaLong loops are. But comparing these two matches we can see ZJK loops are so much faster, when he loops I cannot even see the contact moment between racket and the ball. Given that ZJK and MaLong train with the same coach and use the same rubber on FH, we can see Viscaria is much faster weapon comparing to Long 5. All three players are legends.
