Today I... got "1 turn lighthouse" after a lot of attempts. It's not easy but it's not so hard as "swing in".
I have a theory why is "swing in" so hard to me. I'm feminist. This trick is like this: The ball (female) try to escape from the ken (male), but this one pull her strong and she is forced to come to him It's in this moment when the ken try to abuse the ball, piercing her hole with his spike. So, I'm gonna speak with the superdan 10 of JKA to abolish this trick from the grades, because it's sexist... and it's difficult to me.
