What to buy with frost?

Hey there
So basically on my DK tank i recently got a token for tier 10.5 and im wondering what item i should get with it ( ill need to get tier 10.0 first with frost) or wether i should get the 264 trinket with frost and save for tier 10/10.5 after..

Basically thats my armoury and if anyone could tell me what item is in need of an upgrade most with my frost id appreciate it.
Thanks.

By the Looks of it trinket should be priority, After that i would go with tier Chest or the Belt, as Tier gloves can be gained from VoA

It appears as though you already bought the trinket. If possible, I would recommend returning it and getting the belt. Not only does the 264 belt give you a large stamina increase, it also has more strength and 1000 more armor.
