Yeah, I know the biggest are the sugar dogs, but for submarine targets, slightly larger hulls are better. Remember that to slide into the campaign, they need to be type 101 (tanker) or type 102 (cargo).
Throw sugar dogs in there, and we'd pretty much have to call them type 104. As type=1022 they don't work (they would foul up convoys, etc). They won't be seen in game in any numbers unless we also make all the traffic. If you look at my old posts, I've been pitching them for a while, but I now think ~1000 tons is the smallest to be on the first order list (The type 2E at 873 grt).
A nice thing about the 2E and 2D (2300 tons) is they look nearly identical.
