Kinda late but iirc a CL is needed for branching rules, so u probably would need to go to 1-5 with 1 random DD and 1 4-slot CL (CVL and BBV remain the same).

And I'm just curious: why is Abukuma Kai2 not included in the 3-5 South Route composition? She can help clear trash in the opening torpedo phase, and I would assume that high level TTKs will already have her.
