Ladder-pattern & acoustic - how do you like to use them?

[Skubber]

This is picking up on something from a previous thead...

Acoustic torpedoes I pretty much use as they were intended - I'll fire one from the stern in the hopes it will track a threatening destroyer. (Got a frigate that way on my last patrol.)

The ladder-pattern torpedoes are a nice addition to my standard convoy attack.
I'll surprise the convoy with my first three or four shots.
Then I'll use a ladder torpedo for a more distant shot. (Maybe I've just spotted a juicy target way over there that I did not notice at first.)

In the late war, some convoys are pretty heavily guarded, so I'm trying some shots from a greater distance. (>1000m)
I try to initate the ladder so that it crosses two columns of the convoy. (Or three in a tightly-spaced convoy.

I've had some success with this, but there's still nothing better than getting right in the midst of all those ships!
