I run TWoS without real Nav as I am not a hardened Sub Simmer. I like to dip in every now & then but find the mod too realistic. I want to play this MOD on easy level, eg. Auto torpedo calculations, (Maths has never been a strong subject with me.) Is this easy to set up to in such a way? I like this MOD over Sobers but find it a bit to tricky. Can anyone help without giving me Boos & Hisses? Thanks.
