Thank you for your feedback guys!
I got really frustrated but i feared it was the shallow depth and the fact that it probably was like this in reality....
About the stiebler patch i wanted to try h.sie and then stiebler but its the 4th time i restart a career due to messing with various mods so i wanted to wait for another career before starting again.
One more thing: i read through the GWX manual and they talk about that a depth charge run would mess heavily with the hydrophones for up to 10 minutes in real life; they say this is somewhat loosely implemented in the mod. So you can actually push at higher speed for a couple of minutes after a depth charge run or its false? The only times i actually almost made it was when i pushed at flank speed exiting the destroyers circle and then slowing down 1 km away. I think they still picked me up with the sonar though afterwards while i was trying to get away at silent speed
As for bait destroyers in 41: i had a couple of encounters with escorts in late 40 off the coast of ireland with my IID. And it was laughable (too bad i only had 5 torps) , dove to 160mt -> depth charge run -> flank 15 seconds ->silent speed BYE BYE . it was too easy
I guess its the depth the real problem
