Obviously the answer to my question is yes, but my real question is: If i wield two light weapons (daggers, wakizashi, maces, etc) and i have the two wepon fighting feat, my penalties are only -2/-2, or the off hand weapon must be "lighter" than the main weapon?
and since it wasn't mentioned, you get the light weapon penalty if you have a light weapon in your off-hand regardless of what size weapon is in your main hand, or even if your main hand is weaponless.
