WHat Srting?

i’m trying to decide which string to buy:100% Poly 100% Cotton 50/50 Poly/Cotton
I’m aiming for long spin times, long lasting string, and string that j ust works well with all types of 1A tricks

I would suggest 100% poly.

100% poly. The string causes less friction and will not slow your yoyo as much. Also, I use 100% poly and whips and slacks work well. But the slacks depend on string tension.
