What you state also doesn't make sense. Wouldn't he plce the tree back in his body if it was the juubi? And why would he damage the Juubi that much if he needs it? And I would say that one super TBB is stronger then the 4 obito fired.What you said doesn't exactly make any sense. Whether it was special tree or Juubi, it still used 4 TBB greater to what Juubi used [You must be registered for see links].
