Naruto would, cause Six of Kurama’s tails would still be more then six of the other one, merely because of how much stronger Kurama is. He, at Nine Tails, deflected a Bijuu-Dama of four other tailed beasts combined.
No. With Math, Six Tails of Kurama is about 5.4/10 of Kurama’s max. This would mean that Kurama at six tails could take on two full power Bijuu. And Naruto is using this power.
Actually 6 Tails would be 3 Tails. Cause it's split down the middle. So a 50% Bijuu countered TBB would be 5.50. Correct but that wasn't a concept back then. You're basically saying Pain > 6 Tails can counter all Bijuus
