i need advice on string type

WELL, i have a yoyojam dark magic, and i am proficient in the 1a style of yoyoing. i want to start on 2a and looping, to branch out a bit. i want to buy the polyester strings for my dm, but i am wondering if it it will affect the responsiveness of my sunset trajectory that i will use for looping? will poly strings be good for my sunset trajectory?

I have poly string in my loop 720’s and it works fine. Just make sure to cut it to the right length!

I think most people prefer cotton when doing 2A but poly will work too
