RUB has totally changed the game for me as well (with the other mods I have installed, too.. can't forget those little ones that spice up the game). I just had 2 unsuccessful runs at a T3 tanker in the middle of a convoy. There's something fishy, as the rec. manual says that the draft is 10.9 and when I set it for 11.9 they still hit the bottom of the hull, at least I think (from listening to hydro). In any case - I've gotten used to throwing a handful of torpedos at targets that I certainly want to go down. On targets of such importance like the tanker, not uncommon for me to fire 3 torpedos. Finally received my first message since I got the game about an enemy warship doing 30knots down by the AM grids. No way I could intercept it.. had to throw down the clipboard and unleash a barrage of common curse words.
I just finished my 3rd patrol, taken from SH3 Commander:

39k for 3 patrols. Much more realistic than the 30k I used to bag PER patrol and then some. I almost jump out of my chair when I get direct hits and all my plotting/calculating pays off. The only reason Im up at 39k for tonnage is because of the HUGE tonnage Large Cargo ships. 17k each and I bagged two of them. I might need to change the tonnage for those bad boys, 17k is a truck load.
