[quote=Schradinger]
The speed I'm talking about has more to do with acceleration and momentum. Yes, it's very fast at the tip, but what if he misses? Then he's got all that weight dragging his swing past the striking point and leaving him open to counter-attack. Even being stronger than most humans, it'll take longer to recover from that than it would for David or Mordem to recover from a similar strike.

Not that smaller weapon means one should take greater risk, the time it takes to recover from a committed blow is such, that regardless of the weapon, you rarely see any one fully commit to a strike in a real sword fight.
