doesnt kakashi say he trained up sasuke's speed up only in the 1 month training in preparation for the chidori?
chidori is a great technique in the right circumstances but not in a close handed 1 on 1 combat since chidori needs some start up run to get the necessary speed.

and i doubt lee would do primary lotus in those circumstances since it destroys his body pretty badly. cant wait for lee to come back in the next arc, its obvious he coming back otherwise why have that stupid part with tsunade geting a 58% chance at success thing.

btw i still think sasuke would win as long as he doesnt use chidori, if he uses chidori he gone for. remember this aint DBZ(no matter what people might say) the strongest move isnt always the best move.
