EH or Avoidance Trinket?

[Lucinam]

Armory: The World of Warcraft Armory (http://www.wowarmory.com/character-sheet.xml?r=Illidan&n=Lucinam)

So my question is, with my gear setup, which trinket should I use:
Figurine - Monarch Crab - Item - World of Warcraft (http://www.wowhead.com/?item=44063) w/ 2 +30 stam gems
or
Purified Onyxia Blood Talisman - Item - World of Warcraft (http://www.wowhead.com/?item=49487)

With the Monarch Crab my stats are:
36.2k hp
23.96% dodge
18.82% parry
17.72% block

With Onyxia Blood Talisman:
34.9k hp
24.37% dodge
20.75% parry
18.28% block

Opinions are appreciated!

EH x Avoidance is an eternal struggle. Define your needs based on the content you are at. For ToC, for example, (especifically Gormok and Anub'arak), avoidance plays a stupidly small role towards keeping you alive.
