Ktkm base torp = 139.

Hyoteki torp = 12.

Day torp damage = 139 + 12 + 5 = 156 => 152 from softcap.

Adding torps doesn't change her day torp damage, reduces her day shelling damage.

Unless you need the full 300 damage at night, dualgunhyoteki > dualtorphyoteki. Even then, guntorphyoteki already hits 300 at a 10% higher activation rate when luckmaxed, so dualtorphyoteki is used only in head-on (rare) and chuuha (rare) cases in which case the stats are 80% and 70% effective respectively, while the general case for firepower is 100% effective the majority of the time. Dualgun doesn't need luck. So Ktkm luck-priority is low.

Abukuma base torp = 94.

Max torp from twin quint + hyoteki = 42.

Day torp damage in perfect conditions = 94 + 42 + 5 = 141, below softcap.

So abukuma needs dualtorp for effectiveness in day.

That means her night battle setup is dualtorphyoteki by default. Which needs 50 luck to be optimal. So Abkm luck-priority is very high.

As if that isn't enough, CLT can be banned from a map through branching rules or a hard ban. Devs can never ban CLs because 1x CL is compulsory for escort fleet in a combined fleet.

See my guides if you need more info. I'm not retyping those.
