Do Valyrian Swords stack?

[Rationalsanity]

So I inherited both the traditional Targ blades and I'm wondering if the bonuses stack for the purposes of duels? I mean clearly the thought of someone duel wielding swords that big is completely out of spirit of the setting but does the game know that His Grace can't use two greatswords at once? I've been crushing my enemies in every duel on the first strike; though I can't tell if that's the swords or only Formidable Fighter + Strong + one blade doing that.

I don't think they stack. I usually do this if I get a son lower in the line of succession with the quick, tall or genius I train him to the kingsguard and give him the sword after. This way you are pretty sure your Kingsguard are bulletproof ( or at least until the plagues come... that shit is clearing house! ).

I know the command bonuses stack, I don't think that the combat does.

Dark Sister was a longsword, Blackfyre was a bastard sword. Considering they're both magically light they should be dual-wieldable by a sufficiently capable swordsman.

I don't' think they stack, just from a quick look in the event txt.

A strong formidable fighter should be kicking ass and taking names even without a sword though.
