And yes SoftWeave Armor from WAR! is fine to use.
With a 3 body and 3 strength, you have an 6 armor limit and -3 to encumbrance for either ballistic or impact. Which you want to give to which depends on how much you value balanced armor ratings versus focusing on ballistic armor (which may or may not be the overwhelming armor used in soak). Also how much does the man on the street care about FFBA? Some GMs restrict when you can wear Full Form Fitting Body Armor while others don't care. Therefore, I'll make 4 outfits, one pro-impact & pro-ballistic and with full FFBA and half FFBA.
