About early war patrols, I think if you are a seasoned Kaleun and know what you're doing you should have no trouble racking up a big score with little comeback. Plus by the time things are getting harder, at least your crew has developed and your boat is upgraded.

Depends on scenario as well. I tried the Operation Drumbeat mission last night for fun and a look at a Type IX for a change. American warships sure are poor at that stage of the war! As for the Type IX, I liked it a lot
