By my opinion Laurance’s Cross over on 2s rotor may sound good in theory, where the time of rotor matches the time of last ball rotation. Problem is that you still have some mistakes with rotor clocking on such fast rotor. Another problem is the ball traveling time deviation.
Even if you predict with same amount of rotations to the end of spin , the ball traveling time to your dominant diamond may deviate 0.5-1s. Even it is 0.5s on such fast rotor it would make 9 pockets mistakes. As you said jumps may be more chaotic, so your advantage may drastically drop.
