Recently I've aquired Renatakis TF normal, and I don't really know which trinket to use as the secondary. Valor trinket or Bad Juju LFR? I'm guessing the second is the better option, but I'm not reaching haste build anytime soon, at least before I get 4pc.
I remember getting my heroic Thunderforged Bad Juju, raiding with it for a week, and then looking at the logs to calculate uptimes and seeing it close to the valor trinket in terms of the agility proc. This was around 530-ish item level with a crit build however. I don't want to give a definite answer based on my previous experiences as it may have been bad luck, but I think the valor trinket is far better as long as you can actually use most of the hit. Looking at your armory it seems like you won't be wasting any of the hit so you should be fine.
It's a completely different story with the haste build however. But since you said you won't be using that anytime soon I would just stick with the valor trinket.
