Though very long, the trips to the Carribean are usually major hauls. If you can sneak into Curacao sometimes you luck out and there'll be 3 or 4 T2 or T3 tankers sitting there. Plus along the way good 80% of all the traffic are tankers. Though the IXD2's dive time is the worst, if you actually invest in a good Flak crew there is more than ample firepower on that ship to down anything (watching those annoying as hell B-24's crash is so satisfying). Though you almost need to permanently station a repair person on the flak deck, it gets damaged during any fight. Best I've been able to muster so far from down there is 110k, still had 3 eels left but with 4% hull strength left I was just happy to make it home
