i change my mind too much and go through moods, its usually one of a few though. i think a cool team would be sidious with his weirdo but very effective form of dueling and obi wans most conventional and basic. sidious puts so much hatred into every move he makes and obi wan is devoid of all emotion, and style. nothing like dookus grace or yodas flash, just exactly what he needs to do to get the job done. the ultimate sith and the most well rounded jedi around.
obi wan could defend against anything and has never to my knowlege had his defences breached in pure saber combat, and sidious would kill with such furious vengeance. id like to see them engage in purely saber combat, they would be almost perfect opposites.
