What kind of Ultimate Ability does Jedi Master Obi-Wan Kenobi need?

let me settle this, qui-gon jinn used makashi so obi-wan used makashi when he was a padawan but makashi didn't have a defensive element so qui-gon died. Obi-wan switched to soresu after that. In the tatooine battle, obi-wan lured maul by assuming a makashi pose, but he switched to soresu when maul attacked
