Its depends on your connection because some players w/ good connection use full SD but for me much better is 2SD + 3DDR sword is SD ignore Rate+critical ..this only my suggestion
First if you're using Full Options Set with good pot rate do this Helm Armor pants D.D.R Gloves and Boots S.D
Sword: Sd Dec/SD Ignore
In this kind of set and yellow. You can perform your combo well. But be sure you got a good pot rate because you'll be a Jelly ace on doing this one :haha:
Uber Set: Whole Set D.D.R Sword SD/Skill Attack
In this one you can blow your enemy in distance. But be sure that you can recover all the damage that they will done to you
It really depends on your type of play,internet connection and set.Seju explained it very well,so you can choose what's best for you,try different combinations,pvp and see what fits your needs.By the way there are tons of other threads about yellow options,you can read all about them if you search for them
