Pros: Its a wonderful technique. The thin string like chakra would be too difficult to notice. It also covers you from all sides so it can be best be used against Weights users.
Cons: The restrictions are...a bit heavy I would say. Also, when you swing, you momentarily lose the direct eye connection with your opponent. You won't know what happened at that moment.
Usage: I would probably distract my opponent with smoke bombs maybe? And then I'll use this to attack him. Or I think I can use this better in close range combat better. As this technique requires no handseal, I can attack him when he reaches very close and then he will have no place to attack me. Even if he somehow manages to avoid, I'm sure he will be disoriented and would do something that would make him lose his balance. I will take that opportunity to kill him with my bear hands.
Hey, is freeform considered under the 2 turn no taijutsu?
