here's the best movement i could find for breaking the ceiling without using a fb (which is a good option depending on your soul situation), which loses around 0.6s to the fb version (also shown in the vid as a reference).
The idea is that you want to break the ceiling with a side slash (need to make sure you dont wj too early so your slash can actually come up before you bonk) and you also want to hold neutral for the last wj so you are looking right once you clear the ceiling. This will ensure your slash hits the right wall and lets you turn around left without without getting fantad. After that the movement is the exact same in both cases (going right early as we dont have dash).
