im running an IXB career now, this boat is a pig. (i say that with respect however)
this boat requires commanders to constantly remain atop their tactical situational awareness.
crash dives take longer so never hesitate to order one when you need to. IX skippers have to spend a lot of time listening to that little voice in their head when it says "Dont go over there" or "crash dive now!" etc etc.
Im only just getting into 1941 with my IXB so im seeing a lot of african waters and gibralter... and thus a lot of neutrals.
the boat is large, and as a result i think the escorts would have an easier time spotting you on active sonar. (not sure if this is modeled in the game)
With the high torpedo load out you stand a good chance of completly obliterating a convoy in the right conditions.
like all boats it has its pros and cons, i still prefer the more forgiving VII series, but the IX series has proven itself to be an important tactical player.
