Lynx's weapon WAS bigger than Hardwired, i've seen sense and had the new one designed at 250mm...that's sensible...right?

I don't really see the problem only having the disc/drum at 150mm, if it's for HW2 i'm guessing you'll be using it as more of a kinetic flipper alongside the robots speed. Besides how big is the disc on Satan's Mutt? if i remember correctly it had enough power to flip robots up in the air and it was only about the size of an ants bumhole.
