Seems like Dual swords will have same p.attack with 2h sword and fists. they all will get 2SA's. there is no more special SA for +4 Duals. but you need 2 sword and millions of adena to make them just +0 duals. and warriors will get mastery for all of them. is it worthy to play with duals ?
if patt is same or close to same I would go with the ones that has the best SA's for your play style.. that or whichever has the fastest attack speed when equiped..
