@azrael1973: That means naruto still has fast reaction as he was able to sense the rod being destroyed at light speed and dogged the attack afterward, even though the rod saved him.
Yes his reactions are very fast, there is no doubt about that. It's just not a prove for a lightspeed feat, because the rod is not being destroyed at light speed. This would only be the case if the lightfang could totaly ignore the rod made by TSB chakra. But we all know that TSBs are pretty powerful on their own.
The rod protected him for a tiny moment and as it's made by chakra he should have sensed immediatley that the lightfang would break it.
