Metal zero Modds

I just got a metal zero and I was wondering if their is any modds that will make this yoyo unresponcive? if you have any modds then post them here!

I would recommend the Below

1: Cleaning the bearing and use yoyo jam thin oil
2: Remove the friction stickers and replace with 1 Thin Dif pad
3: Use 100% Polyester strings

hope this helps
