i see kimahri as being . . . woteva u want him to be, thats the beuty of it.
wanna steal stuff? take rikkus path!
someone fast? then tidus'!
strong? auron's!
medium fast n strong? wakka's!
black mage? lulu's!
white mage? yuna's!

. . . but i rarely find that he will exceed the character who's path he's taken so i send him into rikku's just to learn steal, then into tidus' for a little speed then into aurons for some strength
