I gonna be extremely bias here be warned
Darth revan as leader. Not to much to say his gifted by the force on his charisma and tactical briliance.
Bastilla shan ( dark side version) i mean... batle meditation... will win alot of battles.
Then you could have Malgus ( a tank)
And also the awseomoness that is Ulic quel droma ( dark side version)
and lastly and not least ill go with canderous, or HK 47, having a non force user in a team it is always helpfull and sometimes can save the day.
