Deck gun or Torpedo

[soopaman2]

I know traditionally it was more effective for U-boats to engage with the deckgun especially on single unarmed targets. I tend to play it historically, using my deckgun as much as possible, and saving my fish for warships and striking multiple convoy targets quick fast and in a hurry. I love my deckgun, like a marine loves his rifle.


So I ask you, my fellow Kapitänleutnants, What is your favored method of sending Allied tonnage to davy jones' locker?
