Despite being faster Anuerysmss disc is also lighter and has a far higher RPM (11500 - surely illegal and dubious in terms of physics?) but anyway to get that high will take longer than it will take me to get to my max. I intend to attack his weapon - and mine is the heftier and thus likely to come out better out of any such clash. Obviously keep my wheels away, although the outer hubs should protect them from glancing blows.
