Well this is the thing, in Antweights the cam based systems are just 'walkers' instead of shufflers but you don't get a double weight bonus, just 1.5x across the board which I guess evens it out a bit. I know the Beetleweights are a lot heavier than antweights but they're also usually classed in that insect category too so I don't really know. I mean, I for one wouldn't have a problem with 50% heavier walkers and clusterbots not being counted out after one part has been KO'd but obviously wouldn't want to build either before checking what the official stance is...
