1. This Naruto, where logic and science cannot be applied. Even if it could, VAP will not be ablw to change the trajectory. It is pure chakara non manifested short of a physical form. If im not mistaken, weren't the Hyuga(s) under the influence of the Kyubi chakara? I'd like to see a scan supporting this argument.So, I think it's quite plausible.
3. Yama is one of the strongest projectile attacks of Sussano, I don't think dodging will do any good seeing as no Hyuga shown in the manga has DSM like relexes
4. I don't like debating Yata, because of its lack of feats.
I really think you are underestimaing Sussano. Sasuke beat Danzo and wasn't even experienced with it even though Danzo had one of the deadliest Uchiha dojutsu. The Hyugas only defense against Sussano is Kaiten which would be pretty unreliable because of the vunerability after rotationg. 8 trigram 64 palms have shown no destructive close to being able to destroy Sussano but instead have shown pierecing feats of the human body. The only way I see a Hyuga winning is striking the users Tenkentsu with Jyuken, which most likely won't be happening
