hey all mages (or those that are in the know)...

In a bit of a quandary regarding trinkets.  I have three possible but 
only two slots...lol

Currently, I have the 359 Volcano darkmoon card, and am about to equip 
my last trinket.  A bunch of info I've read has the volcano card ranked 
pretty high up there, and was going to get the 359 soul casket for the 
other slot.  However, I also have enough TB badges to get the 359 Stump 
of Time.  From my numbers I crunched, it seems the stump of time and 
soul casket combo would far exceed the Volcano in either combo.  Would 
this be because the Volcano far benefits a fire spec, vs. Arcane?  I am 
Arcane/Fire now (and mostly play arcane) and was wondering if the soul 
casket/stump of time combo would be better in arcane, and soul 
casket/volcano in fire?  erg...my head hurts.  Any suggestions?

2300 valor points and 125 TB badges are a lot of work, and I wanna get 
it right.  I already have 2 pcs. of the firelord T11 set, and only the 
Ring, back and trinket I can really use from Valor points until I win 
some dang marks from a drop in raids before I can get any more T11 stuff 
items.
