I can think of:
-sides with different ano
-kk bearing
-good grinds
-massive, huge, incredible, gargantuan, immense, and hefty rim weight
-an inwards curving body from the rims to the bearing
-a tight-ish bearing seat
-a shielded bearing
-replacement axles
Some kind of replaceable rim protecter, like that one yoyo with the interchangeable delrin rims (the Donut? Oh, and the NoΩstar)
-a rim protecter that is good for grinding
-packaging that comes with Hi-Chew
I’ve tried 1/2a quite a few times. Every time the unbalanced weight just makes it turn in circles, making most tricks involving the yoyo virtually impossible. You seem to be pretty into it, so could you give me some tips on what you can do?
That’s why I wanted a huge amount of rim weight. The more stable it is, the slower it will rotate. Also, the closer the weight is to the center, the less downward leverage, so slower rotation. So, a small, stable yoyo would be best.
