This shows that flails are more effective! The weapons stand up to more abuse against tough things (like against a chain link fence, or razor tips against a 70kg hammer), they do more damage (cutting through plywood, or eating up bot armor), and that 8 is the best amount of lines (or weapons). I think that they'll end up with 10 or 12 on there one day though.
Yes I say this jokingly, but it is honestly what I thought when I first saw the commercial.
