Strenia, my suggestion to you is that you choose Armour based on the actual Mobs you are hunting.
This may sound obvious however your target Mob is determined by the Skills your Avatar has, which determines the weapons that you can use, which determines the Mobs you can kill with 6-12 hits.
I advise that you do some research using Entropedia
http://www.entropiawiki.com/Chart.aspx?chart=Mob
Once you have a list of a few mobs that you can kill fairly easily, you can see which, if any has a Mission associated with it, again using Entropedia, then look at the loot they drop and hunt the Mob that has the Loot with the highest Weekly MU and ideally a mission with a reward.
Only once you have all this detail can you choose armour/plate that defends against your chosen Mob.
So, Skills --> Weapon --> Mob --> Armour.
Of course if you have lots of PED then ignore all of this and fill 'yer boots with whichever Weapon/Mob/Armour combi that your heart desires
Best of Luck
Really not in favour of new players using armour. They get hit a lot and defensive costs are relatively high. It encourages them to hunt above their level. Better to hunt naked choosing mobs you can finish without dying, then heal naturally between kills if you are patient for use an eco level fap if u are in a rush.
So I would agree with the post suggesting no armour till adj pixie.
Fully agree with this, except the healing part unless you really are on a low budget.
