OK so I have 3 trinkets. Which 2 to use for fire and which for arcane?

My 3 trinkets:

http://www.wowhead.com/item=113984/b...ible&bonus=560 (normal warforged)
http://www.wowhead.com/item=119194/g...tory&bonus=566 (heroic)

And I'm reeeally confused, which ones should I use for arcane and which ones for fire. My bet would be:
- shards + repository for fire
- shards + crucible for arcane

But I'm not sure, anyone who has any idea? Crucible seems really good, especially for arcane (dem multistrikes on crystal supernova, anyone? :P) so I'd think even with 9ilvl disadvantage it might still be better than repository.

You are thinking right mate. That's all.
