I think this is close to optimal extern build for dnc. Only piece that really is hard to tell is body, tossup between Athos's and Toci's, however I have toci's atm so that's what I use. Triple attack and double attack are both really really nice.

I also am using merman's + brutal in my ear slots atm, since the upgrade from 6 attack to 4 agi is only small and definitely not worth 3.5 million gil, as well as inventory-1, I use mermans for my -mdt build so I already have them, so that's more of an inventory space thing.
