Nice introduction
I can tell you're very much into it and that's how it should be, ut creates a nice mood for the hunt!
As to torpedoes, be patient, don't rush. Observe your target, wait, you'll most of the time have a better occasion to release your eel than you first think about firing. T1 is a good choice, I don't take anything else and now it's February 1941 (GWX kicks ass now). I love those quick snap shoots only using my eye and experience to set TDC just after brief observation! On my last patrol I've sunk 17500 tons tanker with one torpedo into 1/4 from it's stern, from 2km (calm sea but very poor visibility but somehow I've recognize it)!!! In high seas only use impact triggers at shallow depth so they want bounce from the bottom of the hull. It's not effective but there is no other option. 2-3 eels stern, mid and bow should sunk even the biggest mot******er around. If you use magnetic ALWAYS check with recognition manual to set proper depth.
Gutte Jagd!
