I think Maul could repel the four arms of Grievous with his staff. The staff is extremely effective for defense
ummm, have you ever fought before with any kind of staff?
extremely difficult to defend urself with actually. a sword (or 1 sided saber) is FAR! superior in defence then a staff is. especially a staff where the middle cannot be used for defence. the saber-staffs greatest flaw is defence, it loses defence for offence.
