I would go for Tone-class -> Crane -> Crane -> Tone-class -> Fusou

last event you need at least 4 CAV for shiplocking,  but if you go for all easy on event then Crane first...

take note that on the last event it because of historical branching that you need 4 CAV, so I don't know about the next event but to be safe it's better to have at least 4 CAV...
