Kitakami already achieves near damage cap numbers with double attack, successful TCI is only a bit stronger while failed TCI is far weaker and less accurate. At 30 luck she only has ~45% chance of performing the cut-in, add 5% each for searchlight and possible starshell. Meanwhile DA has almost 100% activation rate.

Assuming the weakest setup with two 15.5cm guns we have 63+139+7+7+12=228 yasen firepower which means 2x 273 double attack. Meanwhile TCI with two Quints has 238 yasen power which means 2x 307 TCI after taking damage cap into account.

If you have good guns (like +9 20.3(2) or 20.3(3) at +4) and the night scout is activated, the DA power rises to 2x 291 while TCI with night scout and upgraded Quints or Sextuples would stop at 2x 308.

As you can see, difference in damage is quite small while activation rate is almost twice as high for double attack.

I wouldn't use TCI on Kitakami even if she had max luck, unless the chance of her falling to chuuha (+20% cut-in rate) was high. This risk is very small in Suijou Butai though. Personally I go with OTO, 20.3 (2) or 15.2cm (all +max) on my CLTs depending on mood.

Lastly, double attack setup is better for her shelling performance, increasing both firepower and accuracy while the torpedo attack isn't really affected because she hits the damage cap with just the midget torp anyway.
