His technique is not stable enough IMO. He needs to be able to play with tremendous spin when he's not feeling comfortable. LSD learning to do so on the FH side is what allowed him to make the leap to the top echelon this year, and LJK having been always capable (in fact that's his preferred way of playing) is why his performance is so stable.
WCQ seemed to try to do that in the game vs Faraji, but he could only execute it at ~60% power, a level that Faraji is comfortable with. He needs to be able to loop with 90% power consistently with a focus on spin. Even if that's not his preferred way to play he needs to be able to execute it because when his game is off or when the moment is big and everyone is tight that's gonna be the more consistent shot.
