I have looked at a lot of information (including Ariyala's materia) and I am going to start melding my gear. As of now I have my Axe, Chest and Leg pieces (each is hellfire i230) and none of them have Crit on them. Thus, I am going to meld 2 Crit materia's to each piece. Does this sound right?

Later today I will get a right side piece and I was just going to meld 2 STR materia's to it?
