Excellent choice, but it doesn't change the traffic pattern on either the Fleet Boat (US) or the UBoat (German) side, so that remains basically "stock". You might see some activity once you get up around England, but once you leave the Indian Ocean going West, it will probably be rather thin. When you go to try it the first time, have "Unlimited Fuel" turned on, because there isn't anywhere to get fuel enroute... If you do decide on doing the trip, let us know what you encounter, if you would please.
