@Ninja That's true, however; Jiraiya had to use Ma and Pa because he didn't know that there would be 6 Pains and didn't expect a long drawn out battle. Before Naruto fought Nagato, Pa suggested that Naruto use them, but we know that Kurama wouldn't allow that. And what are the chances you have to fight six enemies like Pain at one time.

I was just using a suggestion. But hey, you could be right. Everyone fights different, but most shinobi use it for an extended amount of time.
