One thing to consider, when you hold or swing a weapon, you are putting twice and much strength into the swing than if you were to just use one hand. Certainly a matter of strength and personal style.
Yes but what's the point of strength when the beam can slice through ANYTHING? The only time it would be beneficial would be against another light saber... But at that point because of the beam, the force and agility, it's more about finesse anyway.
Though malgus does swing viciously against kao cen in the Return trailer.
Ah well, fun discussion...
And to the guy that makes his own sabers.... Umm... Wow. Detailed reply at least!
