Hydross AoE- Frost

[Menardi]

OK, I know there's heaps of Hydross threads but I couldn't find one about this specific issue. My guild recently went through a restructure in which we lost our Frost tank. We're interested in making me the Frost tank so I was wondering if anyone knows what sort of gear I'd want besides the Iceguard pieces.

I'm sure some of you have seen the video of Hydross being tanked by 2 Paladins. At the end the Nature tank scrolls over all of his gear but I can't find anything on the Frost tank. If anyone has suggestions that'd be great. Naxxramas gear is fine, we're planning to do some runs soon anyway.

If there was indeed a thread that covers this, please direct me to it and lock this thread. Thanks.
