dont the americans have a 1kg weight class aswell? I believe its called the bug or beetle class. Although we have to watch that we dont create too many weight classes as this would lead to the FRA and roboteering community becoming overstretched.

I would like to see more attention given to lightweights and middleweights though because there is a big gap between heavies and feathers, both of which are good but I think it would be good to try and encourage competition in these other current weight categories.
