Not a bad chapter, but i had expected a little more after 2 weeks of anticipation, guy saved it, but i would still only give it a 3.5-4/5. I wanted to see more of Naruto (showing strength) as opposed to breaking his ankle.
It does show something though, Naruto will need to combine sage mode with Kyuubi mode in order to be able to withstand the stress on his body from the extra movement. So sage mode is not dead, and i guess that his Kyuubi power will help somehow in overcomming the time duration issue involed with Sage mode.
Gai having a turtle as a summons is funny, as guy who's life moto is to expend youthfull energy gets such a slow and cumbersome summon animal.
