He struggled with Chidori at first, but he copied Lee's taijutsu with ease
No, he didn't. Sasuke mastered several of Lee's Taijutsu techs in months while it took Lee years of practice.
Sasuke could do it with ease but he's not really in the business of copying other people's moves, unlike fodderkashi. Fodderkashi was trying to mold Sasuke in his image when he was a young and impressionable kid by making him copy everything but once Sasuke was free from him he liked to do everything his own way.
Sasuke in his own mind probably feels that he is too good to copy other ninja's moves and he's probably right.

So he can learn FRS ?
So we can agree cool down will never be a factor when he gains experience ?
