what are good colors to use in the making of yoyostring?

hello all… just wondering what your string preferences are(color, length, intial tension, ect.)

Belly button length, neon green or orange.

Kitty regular is the bomb!

Neon yellow or green poly, not too tight and above belly button length.

Green, chest, good tension, slow, thick, and soft are what I like.

Kitty slicks, black and white. But sometimes I use Poly in white/blue/orange or white/green/purple.

thanks. i am trying to get input for a friend who makes string. he loves the string that he makes but its made just for him realy; it would be good for him to expand the varieties that he makes
