@JCarter426 Further experimentation reveals a lot is determined by the WeaponWield column value - more than just how the weapon is held. With all other columns being the same as a Long Sword, the Double-bladed Sword is still unchanged. However, changing the WeaponWield column causes it to behave exactly the same as a Long Sword - becoming one-handed, losing its balance property, and of course changing how the character holds it. At this point I can give it "balanced' by changing the WeaponSize column, but I'm thinking there is some sort of default for things that take up a mainhand and an offhand. For instance I can change weaponwield of a repeating blaster and it will gain the balanced property twice over...
