My first reply wasn't really a response to your post, just the thread in general.
But, no, I'm not familiar with the 177. But, I do know that the 111 was produced in greater numbers and played a larger part in the war. Plus, honestly, I think the 177 is smurfy whereas the 111 is among the coolest bombers out there (the engine cowlings are awesome!).
The He111 was used to launch guided anti-ship missiles too, by the way
I knew I was going to run into trouble with the 'decently armed' statement. What I meant was, out of the Luftwaffes highly produced, main bombers (Ju88, He111, Ju52,.... erm... yeah) the He111 was a bit more cut out for the job defensive-armament wise.
