DPS boots better than crafted Tank boots?

[Vittorio]

I'm wondering if these DPS boots http://www.wowhead.com/item=51915
would be better than the crafted 264 tank boots for my tank set seen here http://us.battle.net/wow/en/character/arathor/vittorio/ because of the increased Stamina?

I'm seeing that by reforging I could get a few more points of mastery out of the DPS boots as well. The only reason I'm posting this thread instead of using the DPS boots is because I'm looking for someone to point out a good reason why I shouldn't that I may be missing.

Due to the extra armor on items nerf, I'm finding more and more DPS gear that is better in terms of EH than tank gear. You do have to weigh out the avoidance losses though, as a drop (1-2% avoidance) without a makeup in mastery is not a good trade unless you are looking at a substantial EH upgrade.

Yes I've already changed my gear. I'm going Mastery over Avoidance, especially since now you don't need to dodge or parry to use Rune Strike :) Albeit when Cata hits most of the initial questing gear will even be better than H 25 Man ICC gear lol.
