Which Primal Trinket for Ret PVP?

[Mister K]

My focus currently is 2s with a Mage but soon 3s.

Which trinket to purchase? My current one is a 558 crit trinket, anything will be a VAST improvement.

First one for the on-demand burst, imo.

[Tangra]

The first one by far. The on demand health is a joke and crit is bad.
