Just curious as to what trinkets we as prot warriors should be looking at in this current tier pre heroic mode ToT? I guess like maybe a top 5 including rep and boss drops. Having trouble myself trying to figure it out as we do not have Lei Shen down yet sadly. I am using normal version Fortitude of the Zandalari and Lao-Chin's Liquid Courage. Is it more situational to run double mastery in ToT or more beneficial?

Really there's no "right" answer for tanking trinkets because it his highly variant on what your other gear is like and what boss fight you're on. If there's tons of magic damage then your mastery trinkets will be next to useless, if there's tons of physical damage and you have enough stam, then use a mastery trinket. If you still really need hit/expertise then a trinket with that on it and a good on-use works, etc. etc.
You really just need to analyze it on a per fight basis, those two things should give you a great starting point though.
I prefer not to use hit and expertise trinkets, as hitting caps gets annoying when you have to reforge for each fight depending on the trinkets used.
