I put some of these tricks into action in the field, and they seemed to work pretty well.
I'm still working on my intercept skills...to give you an idea of about how efficient I am: Hand a gerbil a pencil and tell it to draw precise lines on a map, only after you hit said gerbil with a baseball bat.
Actually, scratch that, the gerbil could still plot a better intercept than I can...
Anyways, in the midst of testing my plotted intercept courses I recieved a radio report from U-43 about a large enemy convoy near my area. ALT-Tabbing the hell out of my game...(scary I know

) to read some tuts on plotting the intercept courses, I found it worked...and I came up RIGHT in the middle of what had to be 20+ ships...Not a single one armed! While I was busy picking out the juciest close targets, this corvette comes out of nowhere and runs right over me...thank goodness he began dropping depth charges AFTER his screws tore up my aft deck. I'm 100% sure he damaged his engines on the deck of my boat...
So Narrowly avoiding an express tour to the bottom, I fire my last shot and begin a dive to 70M (Ocean floor is at 80M it looks like)
Rig for silent was already active but after I dove I manually adjusted to 1kt speed as suggested, and I'm happy to say it worked. All four torps hit, taking out 3 ships.
I sustained a hell of a lot of damage though, but not from that corvette. He was off depth charging in a circle in the center of the convoy's columns. The damage was because a ship exploded directly above me...chewed up the conning tower and chipped the paint... hull was reported damaged but no leaks thankfully....
I went back to base with some good knowledge of the destroyers and how they work. This is definitely a great mod...one to keep you on your toes.
