Hello sh5 community!

Well, I'm coming from SH3, recently finishing a mod I made. Kind of new to subsim but decided I'm getting into SH5, until a 16:10 Gui comes out.. So hello to everyone and a few questions...

I would like to have a very realistic and challenging experience as possible with all the bugs, worked out so what mods do I need? The only graphics i care about are torpedo hits, FX_19, and Real environment.. I want to incorpoate UI-boat with my mod soup.. So could you help me out?? It will save me 3 days with no sleep trying to get a steady game to work hehe
