water chakra? 
Ok i jump towards your clone again at very high speeds and then turn my arms into sword shapes whilst charging chakra into them and then bring them down crashing into your neck sending it asunder as your clone poofs due to shear pressure of it...
Well for the later techniques you will learn water chakra is needed to make the opponent get choked and gets heavily breathing, so why not here. When chakra is mentioned I belive it's refered to water chakra, and yet again you didn't mention it in what you did even though I told you to do so...
Follow my sayings. This time I will let it slide, next time, don't count on it to be honest.
