Wait, the current Raikage was the last Raikage's B? That doesn't sound likely to me at all. Remember that the current Raikage is the last Raikage's son. That they would wait until the current Raikage was old enough to finally take on the challenge of becoming B doesn't make much sense. And that they would choose the next Raikage just based on whether they can do a successful double lariat?? No way.
