Best gear for a PLD at varius levels

[Darius]

Hey I was wondering, at and after level 30, whats the best gear for a PLD to be using to be most effective?

I just got 31 last night and im currently using:

Kite Shield (def 8)
Centurion's Scale Mail (def 23 / +1 vit)
Eisen helm

And various other decent gear. I know theres better gear though so Im asking for help on what I should look for and at what levels should I be at when its worth upgrading?

Thanks!
