@Dimension Creator Naruto adjusted his Rasenshuriken's size to fit his need, whether it be big or small. So your Shadow Clone example doesn't work so well.

Naruto doesn't use a variety of techniques because he doesn't need em. Rasenshuriken is already such an advanced and powerful technique. If he needed to blow something away, he has other methods (Kurama's shockwaves, physically using chakra arms to puch away, etc.).
