Metallic color strings?


I am becoming more and more interested in making yoyo string since i started making replacement strings for my Mighty Flea. While browsing my local store I cannot help but seeing some metallic polyester string.

My question is, if i use this polyester in some yoyo string is there any chance of it scratching or scraping my yoyo?


Does it feel scratchy? If not it should be good.
