HA belt and body don't drop until t9, I thought I read a post that stated over-melded head has a higher stat weight than HA and Unweathered, but you might want to wait with Crystal Tower 2 coming around the corner and see what the new gear stats are, as the head and body can potentially be very pricey with the number of T4's you have to over-meld to make them worth it.

I've made the belt, but (casually) focusing materia now on Novus.
