What would be your "6A"?

I can see double dragon being 6a… Or would tha be a subcategory of 1A?

3A, but with a twist: syring is tied around the axle. No sleeping.

Either that or two-man 3A, whete each has a yoyo and they aren’t allowed to touch there own string with there NTH.

so kinda like this but with 2 yoyos?

Yes exactly! ;D

Offstring with 3 counterweights. One on each side and one sliding in the middle.
