Theory:
 * the reason why there was no sand in Jinton: Rasengan is because Naruto took Jinton chakra molded by Shukaku and added it to Rasengan
 * the reason why there was sand in Jinton: Rasenshuriken is because Naruto didn't use Jinton chakra molded by Shukaku, but added Doton chakra to his (Fuuton) Rasenshuriken and the wind cut the earth into sand or so.

This is obviously just a crackpot, but the databook has made more harm than good and I don't really care anymore. Blaze Release gets removed, Jugo's kekkei genkai gets removed, all just because of some idiotic book that took half a decade to make and isn't worth it.
