WoTLK R Pala question

Just two questions here.
1) In 277 gear and ~6500gs what libram is better : Libram of Three Truths 264 or 245 Libram of Valiance?


2) Trinket setup : 284 STS + 258 DC isnt better than any of this + Tiny abom 277? I Heard that Tiny Abom is by far best choice but dont know why...

Weapon is Glorenz, no SM

ty

1. Three Truths is better if you don't lose any stacks due to movement.

2. It procs seal damage, so it's worth a lot more damage than it appears.

OK thx. If i gonna get Tiny Abom what should i use with her in couple - DC or STS? No Sm, agility offset
