Which node farming punya setup you want to refer? Prinz or Zeppelin?

For M node (D E F I K M):

Combined Fleet: Surface Task Force

Main Fleet
1CV (Zuikaku Kai with 2 Reppus + Egusa red bomber + Saiun)
4BB (Red gun + Yellow gun + 1 seaplane/bomber + Type-3-shell)
1CA (Maya full gear AACI with best anti-air radar, last slot should be Type-3-shell)

Red gun => any red gun which adds Accuracy, firepower is not really needed in combined fleet. EG: Prototype 41cm +2 accuracy.
Yellow gun => Literally yellow color gun, such as OTO cannon/15.5 yellow, which add decent firepower and accuracy
Type 3 shell => Crucial for installation boss AND wiping PT imps with scratch damage easily(about 50-75% hit rate)

Note 1: Why use Red+Yellow cut in setup?

Normal cut-in setup is far more accurate than Day-DA setup in combined fleet due to Overweight penalty on > 1 big red guns is being amplified in Combined fleet setup.

Note 2: Why red bombers than Torpedo bombers on CV?

CV with red bombers will auto ignore installation-type BOSS and wiping the small ships, even PT imps(with about 50% chance during Shelling-stage, or during Aerial Stage)

================

Escort Fleet

1CL (Abukuma is best due to requirement fulfilling + launching pre-shelling torpedo ability)
1CLT (Ooi/KTKM best due to their insane torpedo stats)
2DD (Requirements, and for 100% countering PT imps)
2FBB (Requirements, and dealing 100% KO damage to Hime)

Equip setup:

Abukuma & CLT ==> 1 HYOTEKI + 2 SECONDARY cannons (No OTO as this weapon got penalty on any CL-class ships), best choice: 8cm green/90mm green/10.5 cm green/15.5 yellow/15.2 improved +6
DD ==> 2X main/secondary(green) cannon for each DD, for their last slot, 1 search light & 1 rocket launcher on your choice, 100% kill on PT imps
FBB => Normal cut-in with Type-3 shell as describe above.
================

Estimated bucket cost on EASY => 1-3 depend on morale, please make sure rest your fleets 5-8 mins between sorties, do not repair and quickly send out again for sorties, even the mamiya word not flashing, some ships within the fleet still not recovering their morale back to normal.

Final Dance E4-Medium

I combined S1 Taufu's setup(HARD) and my own setup(medium), because he got a hella tons of better equipments than me~


Support Fleet

Somehow I survive till BOSS node with a Chuuha'ed Hatsushimo

A bit over kill though:

A perfect balance point between firepower & ASW ==> Day battle finished off the SS-HIME

Of course this is the reward which everyone advised me to clear E4 for MEDIUM:
