Okay I need to go do other stuff so this will be my last post. I just want to say that I thought this debate was really fun.
Fakes
Saying that the mold is the same is not enough. I a fake is called a fake then it is generally fake. Therefore testing with fakes is like testing with a rock you found on the ground. It is not a Beyblade.
Science
There has been an argument that friction does not impact attack power. The examples were hitting people in the face with rubber and then plastic. That argument is not viable though because there is no opportunity for friction to occur. In Beyblade, the two beys in the stadium rub against each other which creates friction unlike someone hitting someone else in the face.
I saw the earlier posts and I am sorry if anyone took them the wrong way. I am just having fun and was not trying to be mean.
