Back in WotLK, I tanked heroics for instant queues after Ulduar, it was pretty easy to tank heroics wearing kitty gear and I picked up tanking gear as I went on. After Cataclysm hit, I didn't play much but slowly got my cat decently geared and now with the Call to Arms bonuses for Tanks coming in 4.1, I'm thinking of going to tank but was wondering if it would be difficult to tank in my current cat gear? if so, what kind of quick tanking off-pieces I should be looking for (neck, ring, trinkets etc?). I know my health pool in bear should be enough, it's at about 150k when buffed in heroics but not sure if I have enough dodge etc...

TL/DR; want to try tanking using cat gear - if it's not a good idea, what kind of gear for quick upgrade I should be looking for?
