Ducimus, you're really making me think here! LOL A VIIB is what I'm running now (January of 1940), and quite frankly, I find myself wanting to sink the C3s, T3s, etc. (ran into a KGV battleship on my second patrol north of England...put four torps into him and he didn't sink
) but putting 2-3 torps into them just isn't worth it with the VIIB's low torpedo capacity. So if it were me, I'd go for a IXB or IXD2 (granted, it has the longest dive time, but all those torpedos...::drools:: ).
