Giga Guess, when you see this, you have a choice of four armors:

Corpsemourne

A general, all purpose armor, recommended
I think you should take this

Leviathan
http://www.battle.net/diablo2exp/ite...e/uarmor.shtml
May be slightly out of range, but can be socketed, and reduces damage
Also, if it raises your Merc's Strength by enough, I'll make a CV Insight

Griswold's Heart
http://www.battle.net/diablo2exp/ite...riswoldslegacy
With your choice of Perfect Gems to socket with
Also, if it raises your Merc's Strength by enough, I'll make a CV Insight

Fortitude

That is, if I deign to find a good 4Os armor, and want to get you that Lo rune; by far the best choice
Assuming if I care to make one, of course
