DK Tank Choice of specc?(ulduar 10)

[Waogun]

Hey,
Ive been readng alot of threads in here about choice of specc as dk tank, but all ppl post diffrent solutions and im pretty confused since im a beginner at tanking.
Ive started to Mt Ulduar 10 but we find my threat way to low atm so i figured i might have a respecc to do something about it.

You can have a look at my armory to help decide wheather or not i should respecc for mt in ulduar:
The World of Warcraft Armory (http://eu.wowarmory.com/character-sheet.xml?r=Talnivarr&n=Cirith)

I had no problems tanking ulduar 10 until thorim came along, then im pretty out of order. It might be the difficulty to but i figured a change of specc would help!?

Change your spec to something like this The World of Warcraft Armory (http://eu.wowarmory.com/talent-calc.xml?cid=6&tal=0055020000000000000000000000305050003520330003 0125111351005200000000000000000000000000)
and change your rune strike glyph to the obliderate one.

Throw in rime procs during the dumps.
and dont be afraid to throw in an early frost strike to capitolize on killing machine procs.

Can you be more specific with the issues on Thorim? Are you struggling in the Arena, in the tunnel, or MTing Thorim?
