Considering Naruto evolved the Rasenshurken after learning the sage chakra why wouldn't he use his new attack when not only is it a bit more powerful thanks to sage mode but also can be thrown?

The real issue is that this technique probably should have been used last or sparingly to take out a few members. Outside of the 5 pains, Yahiko's body seemed to the the toughest and naruto only beaten him using basic rasengan's after his Kurma seal was reformed.
