I also expect that the best yoyo for a person will depend on context. Both ability, and use.
As a noob right now, I like using a full size ultra stable long spinning throws to help learn new tricks. It makes it less frustrating when the yoyo doesn’t go off axis super easy. Also, after I learn a new trick, it is fun to shift gears and move to a smaller lighter yoyo to improve my accuracy. So which one is better?
Also, I love playing with the variety of yoyos I’ve already accumulated. They all have their own character.
I bet top competition players want a yoyo faster than the one I throw with to perform with.
So best is going to change from living room to stage, and from beginner to advanced.
