Well, after putting down the books and starting a u-boat campaign just to see what's new, here's my personal take on it.
MOD- TMO with u-boat campaign enabled, RSRDC, Optional mods from PE3.
WHINING, COMPLAINTS AND OTHER PET PEEVES
1. I'm getting that flying sub again in bad weather;
2. I'm stuck behind valves in the control room in the u-boat;
3. Since when the members of the Kreigsmarine spoke like they hail from Wisconsin?
4. Somebody forgot to place the icon for Clark Airfield in Manila. I think the Japanese captured and used it, right?
GREAT THINGS BIG AND SMALL! (No I'm not talking about THAT you perv!)
1. PE3- great environmental mod. The seas, skies look fantastic!

2. Although I'm no lover of the Germanic drive to enslave the world I find the u-boat campaign so far enjoyable.
3. Now I don't have to restart the boat when I load up a save game. The boat now continues to sail as normal;
4. No more jello water when I come out of TC;
5. Glad for the Night Scope in the US boats. Also the green cross-hairs.
and now back to the books!
