Always good to see an update, even if this isn't the best of chapters. I am glad the author had the courage to change the wave events some, unlike so many other stories that are afraid to even change the dialog. On the other hand most of what happend wasn't all that major and the changes were mostly cosmetic in the long run.
Still it is nice to see a smarter Naruto for a change, so many 'smart naruto' fics have him be arrogant as well which counter acts most of the brains he might of had. So many stories have naruto charge into the dome of ice mirrors either out of ignorance or arrogance. This is one the few that actualy had him plan something decent and logical out.
