Arcane PvE trinket choice?

hey I'm completely torn when it comes down to deciding between these 3 trinkets to use.

I currently have the foul gift of the demon lord trinket,
RF Will of the unbinding
RF Insignia of the corrupted Mind

Which 2 would be better for PvE arcane mages? thanks.

Not that hard to find with the new search feature on the forums...
Sorry didn't know :x
I believe that thread was referring to Fire Spec only.

Still haven't seen an Arcane trink list.

DMC:V
Moonwell
Mirror (heroic)
SoW
VPLC


pre 4.3 trinkets for arcane mages

Is it just me or is the mana reducer trinket off Sinestra still BiS for arcane with a close second of VPLC?
