Yubari as flag with FULL ASW equipment, and buring 2 guns 2 radars on CAs since it is unable to cut-in during day battle.

If you really want to complete the quest, sparkling your ships is suggested to reduce the chances to get taiha, however, usually the fleet will not achieve boss node easily, sparkling may be waste of time.

Choose double line formation at the boss node and hope it is not a T cross down, diamond formation can be considered as well to increase the chance to sink the sub.

Good luck.
