If you're not using any of TDW's great mods, may I suggest you get this one for the spread angle... F_cherschusswinkel - SalvoSpreadAngle_Obelix_edition You might want to fire multipul torpedos someday.
Sorry but I can't find the link right now. Not sure but I think CSP Magui 3.01 now has it included.
