Good slick 6 strings and retailers?

I want a slick 6 string for my yo-yo. What retailers sell yo-yo stings?

I’ve neverseen them anywhere but online. But if you could find a yoyo store around you, I’m sure that they would have some.

are you looking for some in a local store, or online?
not sure where you’re located, but I know the sunshine kite company has some. bought a few from them before. any yoyo store should sell some.
