Yoyo Shape

I was looking at the C13 and the Frantic, they looked really similar. What is the difference?

Also, how does the shape affect the play? I was looking at the fundametals and some are rounded to the egde, others have a lip on the edge that drops off into the bearing gap. do these affect play?

I was reading about highwalling and it says that it leads to increased contact with the side of the yoyo (which I thought was a bad thing) but apparently highwalling is a good thing. Im confused.

The C13 and the fratic are very similar shapes but there might be a bit of a difference. And the frantic sucks and the C13 is good I hear. Shapes like the C13 or frantic can give your throw a vibe or wobble because of it’s intense shape.

The frantic absolutely does not suck.

I like it better than the C13 persnally.
