Typically you want either Stamina, mastery or some other form of heal/absorb as a defensive stats
and hit > STR > expertise as an offensive defensive stats.
Dodge and parry are below average.
The rankings on several sites have either some wierd stat weights or they dont count on use/proc effects properly.
SPA trinket has mastery as passive but the use effect is terrible.
DMC trinkets are typically overbudget and so its this one. It has stamina passive and another terrible dodge on use.
Myself using 2/2 Lao-Chin's Liquid Courage
(but i dont think you should waste your precious valor on it at this point) even though its second best LFR. I didint want to waste VP on average tanking trinket, so i bought the dps trinket which i am using in both specs. Expertise is useful and i reforged 40% to mastery and the STR on use gives me some parry on separate DR than parry rating.
In general most of the trinkets available are supbar for plate tanks. Just pick whatever you feel like - dont contentrate your efforts on trinkets. You cant do much harm or good whatever your decision is.
