Ooi is a good pickup, as well as training up to about 6 DDs to K2 range. Yukikaze is fine at current level, don't waste time where it need-not-be. Ayanami and Bucky are decent DD pickups as well as Akatsuki.

CAVs are more often used because they offer higher LoS over normal CAs, which events tend to have higher LoS requirements. Tone class is also extremely powerful (stat-wise) compared to CAs and can equip seaplane fighter&bomber (zuiuns). Lastly, some maps force CAV requirements into compositions for routing, rather than just normal CAs - while it is sort of rare to see this, it CAN happen. Even if it isn't 'forced' last event had specialized routing to make E-5 easier by using CAV pairs of Suzuya + Kumano or Mikuma + Mogami.
