Patrol Length: Depends, If I spot an Convoy I use most of my torps (when there are a lot of capital ships floating in it) I save 3 Torps on my way back in case when an DD detects I still have some guts left to fire at it.
TC in harbour : Lorient is an nice base...my TC goes max 4 and on some small parts I can higher it to 32 for a small while..
set ur TC in SH3Cmdr to 16. going to fast may result into an total mess when u accidently press an wrong button (crash dive button is the most dangerous one)
About flaks.. Save those for planes...if ur shooting all ur ammo at an coastal merchant...and your in 42 - 45 close by the english coast where happens to be an Airbase....then ur pretty fried fish if ur doing ''Click, Click, Click, ...Crap out of ammo!
