Right.
I think the left is more even.
The funny thing is, I though the right was more “even,” but in a different way. I know what you mean about the left having the splash more evenly distributed in the cup. But, the right has more even distribution of color, a more equal amount of blue and black. Cool yo-yo. I have a YoyoExpert Edition Downbeat.
Of course you do. 
But I see what you’re saying about the splash.
What a beauty
