Generally two stick (I am an SCA guy) is a very tough thing to learn compared to sword and board, in my experience. Some people are good at it, but it is really tough to pull off well. Better than just a single sword, but not much more to say for it.
Then again, no game ever treats shields like a proper weapon. (Thanks, Gygax!

) If I had to pick, I'd take a shield every time, as those buggers can really do some damage, as much as a dagger most of the time.
I am not inclined to mess with the combat rules till I have a number of games under my belt, but giving a shield +1 Fight and Armor and a Dagger +1 fight might be fair. Shields are always better for those that can use them, but many can't so they make do.
