This, nice post netflix. Chopstick I don't believe you understand how the rasengan when combined with elements work. Perhaps you should reread Naruto's wind release training arc.
The Rasenshuriken is Fuuton + Rasengan + Chakra Shape Manipulation(Shuriken), Fuuton Rasengan is simply Fuuton + Rasengan.

Nope, you two may want to go back and re-read though. Naruto's first futon rasengan's weren't able to be thrown but still had the spiral effect on them, which Boruto's is lacking. In case you've forgotten, which it seems you have this is what a rasengan looks like with fuuton added.

It wasn't until he used senjutsu with it he could stabilize it long enough to throw. Chapter 339 the first time he uses Rasenshuriken and his eyes are in Kyubi mode

If you keep reading to 340 you can see even though this is Rasenshuriken he doesn't throw it

Rasenshuriken is just the name of Naruto's Fuuton Rasengan not just the version that can be thrown.

Skip ahead to chapter 415 and we get Naruto learning Sage mode and getting the idea he can throw Rasenshuriken

The first time we see a hint of a thrown Rasenshuriken is chapter 418

So as you can clearly see, Raenshuriken is fuuton rasengan and was only able to be thrown by Naruto AFTER he learned sage mode.
Also Rasengan already is shape manipulation so claiming Rasenshuriken is Rasengan+shape manipulation is just redundant. It's ok we all make mistakes from time to time but hey look at the bright side, now you have something to go back to that guy who tried to bust your balls about Boruto having sage mode and that wasn't even my intention, funny how things can work out like that.
