Is satining rally needed on a celcon yoyo like the Legacy? Celcon plastic is relly slick, and although it might not end up being better at grinding than satin-finished metal, it is grindable. And I believe satining has its porpose in removing machining marks, which a legacy probably won’t have. You can try dying it. And that’s about all the mods i know for you. But no need for satining.
