but lightning clone uses almost a half of his chakra. and hidan is immortal so he does not 2 worry about gettin hit. if the clone dies kakashi has 2 use his ms.Kakashi usually sends in a lightning clone first to ascertain the persons abilities. With it, he could gain valuable intel on Hidans immortality and his curse jutsu.
maybe kakashi has a good point in winning this fight.
