Onoki + x Kage vs Itachi

[ItachiStyle]

They're different techniques. Size doesn't equal power or chakra use. You should know that by now. He hasn't demonstrated it, so he can't use it. Besides, even if we saw him make 10 rock clones, then use Jinton, we don't know that the clones possess sufficient power to use it (or that he does while cloned). If Mu needs over 50% of his chakra to do Jinton, how will clones with less than that do it? Makes no sense.
