These two are the only 226 plate dps wrists in the game. The first one is preferable to the second because of the socket.
-Yogg 25 Norm tier drop.
There are a couple other which would be good, but this is the fastest way to 4-piece tier.
-Razorscale 25 www.wowarmory.com/item-info.xml?i=45138
This upgrade is not critical as I am wearing a 219 badge cloak ATM. The quest to get the Algalon key also rewards a 226 cloak, however I have not yet started on the quest.
-Sartharion 25 Fury of the Five Flights.
EDIT: Currently have the Darkmoon card.
