Thanx Torplexed...
Yeah, its still early in the war, although I'm not sure of what date it is currently in my career, I know its relatively early because I started my career in the beginning, rather, as early as I could. To get the most out of this go-round with SH4. And have only gone out a couple times so far.
Based on what you said about the Gato's abilities, I think I'm going to accept it. I like the sounds of greater maneuverability and a better AA gun. I haven't had much luck when trying to stay surfaced to take on aircraft. I found its better to just dive. But I'd love to stay on the surface and bring some down.
Your reply was very helpful, and appreciated...thanx again.
P.S. How deep will the Gato go? (TMO 1.6.3).
