Tbb is out of the question.
Bee needs to go full bijuu mode to use tbb and sasuke has already come up against that he used amaterasu. If they were to fight again sasuke is the type of person to take advantage of things like this. Amaterasu will land on bee before he can form a tbb. V1 bee, has also been evaded already by sasuke therefore it would be better if he stays in v2.
A has already lost an arm due to his stupidity. Whether he is willing to risk losing another arm, i dont know but i wouldnt put it past him. Anyway im certain sasuke can mold amaterasu around a full susano, but lets not make assumptions. Lets say he cannot. All of A's attacks are nintaijutsu, he would have to attack sasuke if he wants to injure him, but he would do more damage to himself than to sasuke.
Bee's kenjutsu are close combat and sasuke in v1 will be protected by bee's kenjutsu.
Lariat is also out of the question because it requires contact whether A is willing to lose another arm i dont know. Bee in v2 might get some protection from amaterasu but it will still hurt him.
Ill say draw. A cannot touch him without risking himself. Bee cannot use tbb unless risking himself. He cannot use his kenjutsu unless risking himself. Sasuke on the other hand cannot spam susano arrows because either bee and a can dodge it. A we dont know whether due to his raiton genjutsu wouldnt affect him. If genjutsu does affect him, i can see sasuke fooling him with genjutsu and landing an amaterasu.
