What weight category do the followign fall into: a) cheeky boy legs, b) tracks and c) screws

a)Cheeky boy legs are just a waste of time... youll need the weight to get anywhere with them
b)Tracks, EOs disgression....
c)Screws, when I actually think about it, are more like an omni directional design, they continously rotate to travel like a wheel so I would say the screw method of travelling deserves a wheeled weight limit, nothing more.
