Nope. When Kakuzu use his Doton skin his body becomes darker ->1)Kakuzu's body is only very durable because he utilized the douton mask so he can harden his skin. When he was hit with naruto's fuuton rasenshuriken, he didn't have that defensive ability.

Here you can see that he tanked that hit with his base durability ->

Im talking about explosion itself - it wasnt bigger, nor was the crater afterwards. Yep, Naruto learned how to use FRS with much more proficiency, but the technique itself didnt become more powerful.2) The RS exploded because the third was too durable for it to cut through.
Fanboy? I was the one who provived most links to support my opinions.You know what....this shyt is pointless. You can't tell some people anything, even if it's truth and facts. You know what that's called.....being a fanboy.
1. Kirin itself dont use user chakra at all, preparations for it - yes. I want to say one thing: Kirin overall isnt better technique than FRS, becuase its one-shot and requires long preparations. If I had to choose I would pick FRS without second thought, but if are talking about destruction power only Kirin > FRS.Point blank Kirin is a pointless one time shot that uses extreme amount of heat and chakra....something that Sasuke doesn't have and CAN'T to pull off alone.
