which boots are superior for tanking (icc) current content?

[tankeroshie]

The boots I have The World of Warcraft Armory or Spiked Deathdealers - Item - World of Warcraft with two 30stam gems?

If you go with spiked death dealers and gem with a 10 defense/15 stam gem and a 30 stam gem then you gain 22stam and only lose 3 dodge and 13 parry. Or if you do 2 30 stam gems you gain 28 stam and lose 10 defense 3 dodge and 13 parry. I think in either situation it may be worth it, but you might keep your current boots if you need an avoidance set?
