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.
Yes exactly! ;D
Offstring with 3 counterweights. One on each side and one sliding in the middle.
