Chestguard of the exhausted vs t7.5

[Awesomeez]

What would you do?

The World of Warcraft Armory

that's my armory, and these are the items.

Valorous Dreadnaught Breastplate - Item - World of Warcraft - t7.5
vs
Chestguard of the Exhausted - Item - World of Warcraft

Im using the chestguard of the exhausted at the moment because it has the parry and my dodge NEVER seems to be lacking and the parry is very good.

Thanks for the help in advance!
How much t7.5 is enough? i know there are alot of good pieces that replace it but just what ones do i keep/what do i replace and with what.

You have 303 parry rating and 209 dodge rating, yet you have 20.22% parry and 21.21% dodge. See the pattern? You should probably use Valorous, and read up on avoidance stats.
