Picking Paladin Pants

[Brandonian10]

So, I'm a 54 paladin trying to decide which pants to wear.

I currently have Valorium Greaves:

However, I recently came in to some Crustacean Shell Greaves:

I'm trying to decide which is better from a min/max tanking perspective. The drop in AC is concerning, but my character is already stacked with decent AC gear (Deepwater, Valorium, etc.) but kind of lacking in stamina/hp. I'm leaning towards the Crustacean as a compromise.

Thoughts?

Thanks in advance.
