I don't mean to offend by calling it cheating, I simply can not think of a better term. Anyway's if you could pick one of the various aids in hand to hand combat;
Midnighter's battle computer
Cassandra's body reading
Mister X's mind reading thing
or anything else
Which one is the absolute best or perhaps most versatile that you would choose? Oh and it's not limited to the above choices it can be aby sort of power/ability that lets one basically cheat in a hand to hand fight.
