in episode 209, tobi told kakashi that his raikiri wont work. if kakashi was so smart, he should have noticed that yamato's wood was touching him. that would mean he wasnt intangible and that raikiri would work on him, especially since he was distracted by talking to naruto and that would put an end to the strife. why didnt kakashi notice this? also, in the manga, sasuke's susao'o has six fingers, but in the anime it has five. why?
