Would a plastic garbage bin be better because it would be just a touch softer or metal garbage bin because its metal

Also wind could push plastic better than metal.
[center]Ah, but plastic is bendy, and you need something rigid to roll down a hill in... (I know from personal experience...)[/center]
Metal for rigidity. Plastic would break at the first occasion.
[center]No, they don't break... they just bend, and lose alot of speed.[/center]
