I`m playing GWX and SH3 Commander

.
The thing is the commander has many models of fatigues for the crew
grey wolves8 hours,rub1xtc,rub,no fatigue,defaul SH3
wich one do you use,and how exactly are you managing your crew
curently playing on no fatigue and i want to change it
By the way i went into scapa flow in th begining of the war,and got my hull break and i died

i`ve read about these types of operations,one of these almost got Churchill killed in scapa,thank
god the torpedoes didn`t go off.
Are these kind of strategies viable?(not to really follow the course if you want to,go sink some other ships then return to patrol,and most important to go into ports and scare the nation by sinking its line ships etc etc)
i can`t remember the ship`s name

but if i find it in scapa church is dead i swear it :>
S!
