Yellow!
It looks great. And it plays great too:D
GregP:
I must shamefully admit that I sometimes pick string colour based on the yoyo.
As it turns out, neon yellow or green work well with so many yoyos!
When I can’t decide on a colour, or I don’t have a colour that works… good ol’ white!
The one thing I never do is green in a red yoyo. I just can’t do it. Looks so wacky. The only time green and red should mix is at Christmas time.
I don’t know about you guys, but whenever I buy off of the BST, I ask for string. So I have a rainbow assortment of string.
So I like to use a string that matches the yoyo.
I really like black string on black yo-yo’s though.
Something about me, I have never purchased yoyo string. Ever.
Neon yellow, green, or orange all work for me.
