You know, make a KB, get him to collect Nature Chakra, KB will turn into a toad but can give Naruto some Nature chakra before he does. It's a possible way for Naruto to remain toad free and still perform Senjutsu.
I can still see training with Nature chakra with KBs though. You know, cover a KB with toad oil, get him to almost become a toad, then dispel the jutsu and Naruto gets to experience what gathering Nature chakra is like without putting himself in harm.
Then get 1000 KBs to start gathering Nature chakra. Dispel the ones that are about to become toads... Instant sage training.
For all the people who are sick of naruto using shadow clones, I seriously doubt his going to drop that jutsu, shadow clones is like a bloodline limit to him. His going to use that jutsu for as long as he lives, however i guarantee we will see some new advanced shadow clones techniques. Probably a mixture of new jutsu's with shadow clones
Knowing the kage bunshin technique alone is extremely handy, but as you all know Naruto having the chakra and stamina that he has benefits him so much using it. People are getting into their heads that with kage bunshin all were gonna see is "Kage bunshin no jutsu", bang bow whip slam *all kage bunshins have been destroyed* and then Naruto saying "Damnit!". Naruto will grow smarter using his kage bunshins and hopefully overall once completing his training with the Ni Dai Sennin.

I think he will master the sage arts, but it would be ridiculous if he did it right away. What I was thinking was Naruto would use Kage Bushins for this training instead of his real body. That way he gets experience in balancing all his chakara without risk of turning into a frog. It seems like the quickest way to train with minimal risk.
Though I must say for a while I was getting sick of him using kage bushin all the time. But I realized something. Almost Everyone in the Narutoverse is a one trick pony. The only person who has shown vast amounts of diversity is Kakashi. Well I guess Jiraiya too. I would say Sasuke is a little diverse but at least 70% of his moves are chidori based, though used in different ways it is still the same jutsu.
The next Generation of perverted ninjas is fully prepared to take their place. The line of the Toad Master will never fail as long as there is a will of fire. Rest In Peace Jiraiya-sama, this world and Tsunade were not good enough for you.
I am as far beyond you fanboys as you are above the humans.

Just wondering, if Naruto fully learns the Nature Chakra then would he be able to use all Chakra like fire, earth, water, etc... as these are parts of nature or just suck the energy out of them?
