Tanking gear question- close to uncrush... butFollow

Ok... I am not that great at the math involved here, so I could use some expert help :)

This is me as I logged out last night:

I have the Strength of the Untamed and Andormu's Tear in my bags, but for regular dungeons and heroics, the ones I have on have more Stam, so I use them. I do get a fair bit closer to uncrushable when I switch to Strength of the Untamed and Andormu's tear. I currently have 6 badges (hoping to have 15 in 2-3 days for my libram), and I am hoping to get the Jade-Skull breastplate from Mechanar sometime in the next few days at worst.

My question is this:

Assuming that I get the Jade-Skull, get the Libram of Repentance, and use Strength of the Untamed and Andormu's Tear, would I be better off getting the Dawnforged Defender instead of the Sunward Crest at least for now? I am not sure that I would reach uncrushable with the Sunward Crest. If I would (with the Sunward Crest and the equipment changes described above), then I would prefer it for the spelldamage. However, if I NEED to get the Dawnforged Defender to get to Uncrushable, then I would get that one first. I have not done the math completely, but I am fairly sure that at least ONE of these shields, along with the Jade-Skull, the Libram and the avoidance ring/neck on will finally get me there, but I am not sure.

Thanks!

I would definitely prefer the Sunward Crest for several reasons, but I am mainly wondering if I would need the Dawnforged Defender just to hit the magical 102.4%. I should have exalted rep with SSO in 4 days or so, so I am just making sure that getting the Sunward Crest will get me to that number. If it does, then yes, it is the one that I want.

Awesome! Thanks YJMark!
