Weighted Bearings ??

Nope, I switched my yoyo design from 6061 to 7075 and got 8 extra grams.

Lol try osmium. SHould double the weight or so, if osmium is even on the list

I was referring to changing the bearing material, not the yoyo material.

I think he was just pointing out it makes a difference

Like I said before, a half gram is barely noticeable and hardly worth an extra $10-$50.
