I am about to begin a new career. I want to start in 1939. I am going to choose between either a VIIB or a IXB. In my mind, I am going to change the number of my new command to either U-29-36 or U-37-44 to simulate getting a VIIA or IXA, since I do not believe that historically a young commander would be given a BRAND NEW type B of either boat. Is this correct? I know some started out in type II's but I want to begin with one boat and keep it through much of the war... until March of 1944 when I upgrade to a XXI. Which boat type would you recommend - VIIB or IXB - keeping in mind that I am going to start the war in 1939 with it and keep it until 1944 (I won't be upgrading to a VIIC or IXC). Which type would have the best advantage of survivability? Please, let me know what you think... I appreciate any and all suggestions. I would think that the VIIB would be best because it's range is not THAT much less than the IXB and it is a lot smaller, so it presents a smaller sonar/asdic profile when submerged. Ofcourse, what do I know? I was sunk on my first patrol during my last 3 careers.
Thanks in advance for the advice!
