This is my response to stringking’s comment on FHZ caps.
The caps are heavier than the original ones, weighing about 4g each. I purposely discarded weight rings in the design stage (not too much designing though :D) of these caps and made it thinnest possible as I tried to minimized extra weight on the yoyo. With these new caps my FHZ weighs 67.7g, not too heavy, the caps are for aesthetic purpose only.
Here are the photos:
